Kayaks are very different to a Tinny. You can paddle a kayak out through the breaking surf no worries. You would be stupid to take any tinny through breaking surf. A kayak wont take on water and capsize. If a tinny takes on any water you will be very unstable, and have a good chance of capsizing. All it takes is one wave that catches you off guard, and you're in a lot of trouble.
You say that this 2.5m tinny has a great casting deck. That's all good to have a casting deck, but is it actually usable? I'd imagine standing anywhere but the middle of a 2.5m tinny would be very unstable, and not comfortable to fish from. The casting deck raises your centre of gravity, and on such a small craft, that is a terrible idea. That's probably why its for sale, it's useless. Add an electric bow mount motor and battery like you're planning and it would be even more unstable. Also if you don't have a RMDL you are limited to 6hp, which wont move you at any great speed. If you cannot start your motor for any reason while in the seaway, and the tide is running out, you're rooted. If you don't have comprehensive insurance on it, you risking losing your boat, and all your gear by taking the risk of fishing beyond your boats (and your) limits. Worst case you're risking your life!
Why trade your 3.5m tinny in for a smaller less capable boat? You won't be able to fish with your mates in a 2.5m tinny, you'll have to fish solo. Stick with your current boat. Stick with your 6hp motor. Don't worry about fishing the seaway for bigger fish at the moment, hone your skills on smaller fish in safer waters. Use the fishing tackle you already have and just enjoy fishing. Save your money, and in a couple of years you should have enough for a bigger motor on your 3.5m and add an electric motor then. 
There is plenty of great places to explore around the broardwater, canals, and rivers with your current boat and gear. Instead of trying to target jewies, mackerel and kingies, why not focus on jacks, and big lizards? 
Save your $, stick with what you already have, enjoy fishing and look at upgrading your boat/gear in a couple of years when you have your RMDL.

Also the 250 explorer is only rated to 5hp, so you would have to sell your 6hp and get a new motor as well. Just sounds like so much trouble to sell everything you have to downgrade to a smaller, less capable boat, just to go a little bit faster. 
As you can see in the picture below. ITS TINY!. The bare boat with nothing in it will only do 11 knots with one person. Add fishing gear, fuel tank, electric motor, battery etc. and you will probably max out at 8 knots.
These boats are designed for getting your from your mooring to the shore in protected water, or for fishing small creek and estuaries. Even the broadwater on a moderately windy day, would be dangerous in this boat. If you even tried venturing into the seaway the VMR would likely come and tell you off and tow you out of there. The more likely scenario would be getting swamped by a passing pleasure cruiser and sinking as soon as you leave the 6 knot zone in the broadwater.

Surely this is a Gee Up thread.
If not....
A 250 is a tender for a larger boat. My car topper is bigger. 
Don't mean to sound rude but you're way out of your depth, pun intended. 
Calm days spells busy waterways. 
 
One Riviera heading out on the plane will see you most likely in the drink. 
2 Riviera's side by side heading out.... You're gone. 
It happens regularly. 
 
Ask around the "tinnie fisho's" like you said you would and if anyone of them advises you to go ahead then they are absolute (bad words). 
 
Don't do it!

Gold Coast Seaway. It's an entrance to the ocean from the Gold Coast Broadwater. (bar)
@Mylesfisher, I spoke to an experienced fisher who fishes the Seaway in a 3.5M. He says he wouldn't go in a 2.5M and doesn't often/doesn't fish at the end of the Seaway. He also has a 20HP on the back of his tinny which is a fair bit more power then a six HP.
Cheers Hamish

Very much agree. A 2.5m boat is VERY small and I'd assume would have limited freeboard. The problem with 'good days' is that forecasts can be wrong and conditions can change very quickly, both for wind speed and also direction. Add to that large tidal flow and as others have posted, often very busy boat traffic and the water can turn into a washing machine VERY quickly. I personally wouldn't be going anywhere near the main Seaway area in a 2.5m boat, just not worth it.
It would be worth putting a picture up of your 310 Explorer as some one here may be able to offer suggestions to improve your current set up.

hmmm.... 'on a good day' does not equate with knowledge of water movement, water pressure/force, tidal influences, etc, coming and going out through a narrow exit/entry point.... just saying

If its a traditional transducer without side scan, then it's shooting out a cone shaped signal, and the size of the cone depends on the frequency that you're running. As you can see in the image below, the depth displayed is never the actual depth below the boat, but the shortest distance between the transducer and the first return signal.
You will never get the transducer installed exactly plumb as the pitch of the hull varies depending on the boat speed, and roll changes depending on how the boat is loaded on the day. You're over thinking it. Just install the transducer pointing down when the boat is on the trailer. As long as its not out by 5 degrees or more, you are going to get decent readings. 

If you are under 16 and can't get a RMDL (QLD), and want to go fast with 6HP, you will need the smallest and lightest boat. Even then you will need to keep the weight down (no cast desk or extra people). Not sure how the Tinny Rats on the GC manage such speed in their boats. They're either young looking 16 year olds, or they put a 6HP sticker on their bored out 15HP outboard. 
If I was you and were under 16, I'd look at a Kayak instead for the interim, maybe with a small electric motor. Then when you're old enough to get your RMDL, upgrade to a 15HP on your explorer and then add casting deck and any extras you want.

Hi all
Last Tuesday I packed up some fishing gear and clothes to go to my Grandmas at Yeppoon. We left on Tuesday and after a gruelling 9.5 hour drive (stopped at Childers, Gin Gin, and Mount Larcom) we were there. As we flew along the Bruce Highway I eagerly awaited the sight of the Calliope, Mary, Boyne Rivers, etc, as I always find it interesting to look at them. I would love to give them a crack fishing one day as they all look like they would have something in them. On arrival, I played a couple games of pool and rigged up a light rod in preparation to go for a session in the morning.
Session #1
It was low tide, so my plan was to fish for flathead and cast net at a nearby creek. The tides were very small though, so, unlike previous holidays where there has only been a small channel of water (often holds big mullet), there was still a lot of water on dead low tide. I started off by flicking my prawn lure (1/4 jighead for casting distance) around for about 25 minutes, but after no hits I figured I'd try my luck for some bait while it wasn't too sunny. 20 minutes later I had caught one or two undersize flatties, some Crescent Perch, and Glassies. I went back to flicking my lure, and after ten more minutes of no luck I switched my lure to a Baitjunkie Grub with a 1/8 jighead (maybe the lighter weight would help, I hoped). 30 minutes later I had still managed nothing, so I decided to try cast netting a bit longer. I threw the net for ten minutes for a couple more undersize flatties (all swum off well luckily) and I gave the plastic a few final flicks. The tide was rising fast now so I finished netting when I got 15 glassies in one throw 🤮 and scampered up the rock wall.
"Ahhh, yet another crappy session at Ross Creek," I thought to myself as I walked away with mud all over me.
Quick Stats:
Tide: Low Tide, I fished about 45 minutes either side of the tide change
Moon Phase: 34%, increasing
Fish Caught: -
Lures Used: Holt Production 4inch Swimprawn in White spot and Diawa Baitjunkie 4 inch Grub
Tackle Used: Abu Garcia Veritas 3-5KG, 10 pound braid mainline, Diawa Shinobi 2500, 6 pound leader. 1/4 and 1/8 jigheads.
Session #2
I spent a little while rigging up another rod with a tiny ball sinker and a baitholder hook in preparation for a session that arvo. I arrived at the chosen location and beforehand picked up a bag of prawns from the nearby servo. Normally I would make a better effort to catch bait but the bait at this servo is all good, large prawns (I think they must get them off the trawlers then freeze them themselves). 
Anyways, there were a couple of folk fishing on the wharf I intended to, so for the first few minutes I casted into the shallows/near the rock wall. Luckily for me it seemed they were packing up at the perfect time so I scampered into position. After getting debaited and pickered a couple of times with a baitholder hook, I made the switch to a size #4 long shank hook. It didn't take long before I pulled up two undersize bream (23CM), one of which fought decently as it was foul hooked. 
The wind was terrible so I set up so none of my stuff would blow away. I was struggling to feel small bites because the wind was often blowing too much line out. My third fish I hooked was a bit better though, but inevitably, it wrapped me around one of the pylons. This happened 3 or 4 more times that day - though I believe they were all small bream and cod, and the reason they busted me off was because I was dropping 5cm from the pylon. It was a fair time before I caught the next fish but I did manage to end up getting two little butter bream. Eventually I pulled in a couple more tiny cod, but at about 5:30PM I called it quits. Interestingly, I saw someone throwing a cast net. I never thought there was much bait in the harbour but that changed when I saw him pull up enough herring for a session in one cast.

Tackle Used: Shimano Stradic 3000, 15 pound braid and leader, Shimano Raider 4-7KG. Size 00 ball sinker and #4 longshank
Session #3
The next session was the following morning, at the same spot again. I arrived a little after six, and was the first fisherman at the harbour. A large charter boat (going to Swains Reef, I presume) was unloading/departing, but I can't say that I felt like I wanted to be on that boat. It was so windy I was practically getting blown away!
My Dad and I gave the net a few casts off the first wharf for a couple of lancers and one extremely unlucky grinner (kept for strip bait). We then decided to move locations to the wharf I would be fishing off. It only took a couple of throws before we had gotten a good amount of herring and bony bream (as well as a couple other undesirables). I got to fishing, and my Dad headed off. After a good while standing in the wind, I finally landed the first fish of the day. I think it was a little bream or cod (can't remember). This continued and I got pickered a lot, but to pass the time I continued cast netting. I ended up netting a small GT, so I flicked my soft plastic around for a little while in hope of enticing one. Nothing was interested, so I got back to bait fishing.

Trev
I was struggling to feel any bites and because of the wind my 00 ball sinker was being blown out of the water before it sunk and got into the strike zone of larger fish (enticing lots of crescent perch, my new archenemy). I was excited when I heard a short, sharp run on my overhead outfit. I picked it up but after a short fight I was disappointed to see an undersize cod, which engulfed a bait bigger than it's mouth. I got a few more runs, one which led to the head of a bait going missing, one which led to another small cod, and a third, much more interesting one. At first I thought I was simply snagged, but upon tugging my line I realised I was making some headway. 3 minutes later I had some cutting in my hands from the braid, a huge, rusty boat propeller, and another undersize cod wharfside! Lol. 

The propeller cod
I fished for a fair bit more after that but eventually had to go home so packed up with some fresh bait and high hopes for my next session.

Session #4
I rerigged my rods after the morning session in preparation for more fishing. I was dropped off at the harbour and walked over to my chosen location with my three rods. There was one other kid fishing (maybe 11) and from the looks of it he wasn't having any luck. One throw of the cast net got me around 25 small herring, so I figured I wouldn't bother catching any more for a while. Unfortunately, only around ten lived, which was annoying. 
I deployed my heavy rod with three livies bunched on the hook and put my lighter combo down with a light weight and whole herring. It didn't take long before I was on the board with a small cod - these seem to enjoy munching on herring much more than bream, which seem to like prawn. I continued to get pickered and alternated between grinner fillets (I had some success with small bream on these in the prior session), herring, and prawn cubes. To keep me occupied my overhead would scream off regularly, but they were only small cod gobbling my herring.
When I ran out of live herring I decided to throw the cast net again. One throw brought me about thirty small herring this time. Although it was very tempting I decided to stop throwing the net as I had no use for so many herring. I redeployed live baits and continued feeding fish on my light line. While I was waiting I flicked around my 3.2 inch plastic, and jigged it around pylons to no avail. I caught a couple more small cod but eventually I ran out of livebait, so I rigged up a small dead herring and lobbed it out into some water away from the structure. 
At around quarter past five, my overhead was hit hard. Line was flying off, and I was quick to set the hooks. I did one wind and could feel that this fish was very big. I was struggling to gain line, and after some thumping headshakes I was questioning whether my already chaffed 30 pound leader would hold up. I had about 6/7KG of drag on this fish, but it was still taking some big runs. I was jumping around up the wharf fighting to keep this fish from busting me off, and eventually I could see my leader.
The fish made one final bid to win it's freedom by thrashing about beneath the jetty. Somehow it did not cut me off on the oyster encrusted pylons, and I could now see the sinker. One more crank allowed me to lay eyes on the large, silver, fingermark. Woohoo! I never expected I would see one of those!
The battle was not just over though, and I needed to enlist the help of the boy fishing to land it for me. We both scuttled down the rock wall to a concrete slab we could stand on, and while I held the rod the boy held the fish in the gills and brought it up to the wharf. I must admit, I certainly wouldn't have done that in fear of getting cuts in the gills.
Seeing as though it was my first good fish of the trip, and I have never tried Fingermark, I decided to keep it. I doubt it would've lived anyways as it was quite exhausted and held up by the gills for a long time period too. I bled him out, and a bit after 5:30PM I very happily departed the jetty with my catch. 😄 I gave some of my herring away to a newbie father/son fishing team as well, so they could try with some fresh bait (and so I could get rid of a little bit). 

Happy days!
I filleted the fish up back at my Grandmas, and it was frozen in preparation for dinner a couple nights later.

Session #5
After my successful trip the day prior I had eagerly prepared my gear to fish at the harbour yet again. I was very happy when my uncle offered to take me out on his boat for a couple of hours, as I have always done well off there. Unfortunately, a large rain cell had been reaching Yeppoon, so it was a wet, very windy day to go fishing. 
We got to the boat and set up out of the wind. We were immediately getting small bites, but there was nothing large nibbling. My uncle somehow hooked a ponyfish which I decided to drop down as a livebait. I didn't hold high hopes as I have never caught anything good on a ponyfish but I figured I may have some luck.
My uncle was trying with prawn and grinner strips, and I was sticking to herring. My uncle caught the second fish, a small bream. 2-0! Eventually, after many picker attacks and hit and run incidents (crescent perch), something much better had a go at my bait. It took two speedy runs, but in the end I did not set the hook. I think the #4 longshanks are a bit small for whole herring anyways.
After that I caught three small bream, but my uncle caught two more fish, ultimately giving him the win, 4-3. We went hope wet from the rain, annoyed we did not get any keepers.

Session #6
For a brief period that arvo the sun had come out, so I decided to walk to Statue Bay and flick a plastic around for a flatty. I rigged up my Shimano Cranx overhead rod on my baitcaster, and tied on a 1/4 jighead for casting distance with a clear coloured Ecogear 4 inch Flickbait. Eventually I arrived, and I could not believe my eyes! It was completely packed, at every spot I could possibly fish. It's probably one of the crappier/worse fishing locations in Yeppoon, as there is only a small sandy section (the rest is rocks, just go at low tide to look).
Obviously, seeing as though I was there, I had a few casts. I was pleased with the distance I was getting (25m). After ten uneventful minutes of casting, I got badly snagged. I decided I would attempt to find my lure the next time I was free on low tide, so I left, disheartened.

A badly rigged plastic I found buried in the sand. I also saw some people cleaning a mudcrab they had obviously caught somewhere else there.

Session #7
After that rather dismal session, I decided I would go back to the harbour the next morning. I rigged my rods up, and arrived at the harbour before any other fisherman by a mile. My Dad did a few throws of the cast net to begin with, and nailed some sizeable herring and a bony bream. We also caught our first ever 'Happy Moment', which we cautiously nudged back into the water. I deployed my baits and my Dad headed off. Before this, the wind had briefly abated enough for me to have good contact with my bait. In the prior moments, Dad had caught a Flat Salmon in the cast net, which was released. The same fish quite possibly produced those weird bites, and after some brief aerobatics (a noobs queenfish, haha) I had a badly gut hooked slab of bait on the wharf. I chopped him up and kept him for strip bait. 
The weather was still pretty dismal, and on top of the extremely strong wind there was still a fair bit of rain. I started off the session by doing the normal 'drop the bait 5cm from the pylon and get pickered before it sinks', which lasted for a fair while. I was waiting for the big rod to go off though, and after landing a couple of tiddlers (one of which was a toadfish which ended up dying as a result of having the longshank hook so deep down it's guts 😕) I was feeling down. The flat salmon strips had also produced some small cod.
Upon checking the big rod in the mist of a shower I realized that a large fish or ray had been sitting on the bait. After about 5 seconds the biggun started shaking it's head a lot, which confirmed to me it wasn't a stingray. Annoyingly, it spat my live herring bait soon after! That was enough for me to confirm that I was likely hooked up to a big cod. I was running low on livies so I casted a sizeable ponyfish back into the general area and began fishing with my light line again. 
Between rebaiting, bending over, and ensuring my bait was sinking, or not getting blown away, I had neglected to check the heavy line. After pulling in a couple pickers (cod if I remember right) I was pleased to hear my ratchet clicking madly. I waited until the long, slow run ended before I clicked my baitrunner into normal drag. I would've had about 7-8KG of drag on this fish, but I wasn't making any progress. It went towards the shore, so I maximised my chances by cranking line in really fast. Unluckily for me this fish clearly knew what to do, and began swimming towards pylons in front of the wharf. After a brief tug of war the fish began to strip line quite fast. It would've taken around 20 metres with my line wrapped around the pylon (somehow didn't snap straight away) before I got busted off. Arghhh!
I fished for a couple more hours but could not entice anything sizeable. I got picked up for lunch, wet and chilly, and rerigged in preparation for an arvo sesh. It is also worth noting the prior arvo I left my sunscreen tub on the wharf, and it was still there the next day. Yay!

Session #8
I arrived back at the harbour keen to go fishing. There was no one fishing on the the wharf I like going off to my delight, so I scampered over with my gear and set up. My dad couldn't help himself with the cast net, and gave it a few throws. It was very sunny, and this proved to be good for a couple of garfish and bony bream. I sent these out on two live bait rods, this time, and continued netting. I caught a sizeable mullet in the net as well, so when one of the garfish carked it, and got pickered as a dead bait, I sent him out. I also caught my first ever Sicklefish, which was tiny. (released)

These are supposedly tasty when big
It was terribly windy and there were a few fast moving storms hitting/just missing the harbour, so I had my poncho ready. I dropped my leader to ten pound after a while as nothing was happening, and I was immediately rewarded. It wasn't amazing but was nice to get a healthy bream out of the pylons (maybe 23-26cm).
I continued changing baits (not the mullet, but herring, bonies, etc) when they got pickered, and I tried casting in many different locations. It seemed the big fish were not chewing one bit, and I can't imagine that the wind helped that one bit. It began to get crowded in the harbour, but I stayed to try and get a fish. There were others cast netting in preparation for a night session, families showing kids how to fish, and some float fishing (maybe for garfish??? it didn't look like it though). I headed off a bit after 5:30PM, sad that on my last fishing sesh of the harbour I got none. I released the mullet and my dad gave the cast net a couple more throws for some herring - he couldn't help it 😉.

Session #9
For my final session of my trip to Yeppoon, I decided to try a spot, known as Causeway Lake, which was recommended to me by a helpful/nice fella. I woke Dad up in the morning, and we drove to the harbour to catch our live herrings. The first cast brought a school of scat, which were released/fed to seagulls, but the second cast brought a Chrissy Tree of sizeable herring. We filled up the bucket and drove to the Causeway Bridge. It gets very crowded here, so I was pleased that I could select the best spot on the bridge as I was first in. 
The Causeway Lake has been built so it is cut off from the ocean on any tide that is lower than 3.7M. The good thing about this is that it means that, when the lake is cut off, it doesn't go down lower and lower, therefore meaning there is always some water. The bad thing is that fish from the ocean (barra, trevs, etc) cannot make their way into the lake. There are supposedly resident fish in the lake though, so I figured I would give it a crack. 
After I deployed my livie rods, I dropped a lightly weighted prawn cube down into the water. It began getting nibbled by toadfish and baby bream, so I left it down in the water for ten or so seconds, but it didn't seem like anything big was coming. Just as I lifted my bait out of the water, a GIANT cod surfaced and gulped down some of the fish!!! Wow! It was easily 80CM, and it had a giant, thick head. I am glad I didn't hook it as I would've just left a hook in it's mouth, though I am sure it is a resident cod to the lake and it wouldn't of mattered too much anyways. While this happened, two blokes flicked lures at various access points around the bridge for ten minutes, though caught nothing and left. Weird. Maybe they were just sussing a spot out.
At around 6:30AM, another fella came by. He was flicking lightly weighted baits, and started his day off with a Moses Perch. Shortly before this, I caught my first ever fish in Causeway Lake, a tiny cod - 

🙂 
Shortly after that, the bite went a bit quiet, and some other people rocked up. They were nice enough, but seemed like they wanted to mind their own business/a little bit funny. After a couple tangles due to their lousy casting, and a bit of a cast netting display from the other fishers, I hooked up to my next fish. I was hopeful for a little Mangrove Jack when I saw a flicker of red, but I wasn't complaining when I pulled up another Fingermark (28cm?). Not even two minutes later my other rod went off with a little Estuary Cod. It definitely seemed the fish here came on the bite for short periods, or maybe it was just luck. 


I decided to photograph some fish this session
After that, I kept fishing. I was beginning to run out of live herring, so I started trying to make a dent in my huge amount of deadbait I had accumulated from previous sessions. The fella on the rocks caught a small queenie about now, and my Dad finally headed off (after generously picking me up a big milkshake for brekky, seeing as though I hadn't had any as I had been fishing instead for the past few days 🙂). 
The bite was quite slow, and 9:00AM came quickly. I think I had caught a couple of little breambos, and lost a lot of hooks by then. The snags were bad, so I was slowly figuring out where not to cast. Baits that had so far worked were live herring, dead herring, hardyheads (netted at the harbour), and prawns, but flat salmon was not proving to be any good. The little bream I was hooking were feisty enough to keep me entertained, and on a 4/o suicide hook they were greedy to be eating the bait. At one point the bites were immediate but I was only getting pickered, opposed to hooking anything.
 
Greedy
I continued fishing but now that there was a good amount of pickers hassling me I focused on dropping my baits straight down with a light sinker more. I had a slightly oversized baitholder hook on my Stradic for this fishing, but that did not stop me from landing another small bream or two and a colourful wrasse (which somehow survived despite being hooked it in neck).

Too many photos!
After those pickers, I ended up getting so wound up with all the snags I switched to a shallow diving lure (as it was quite shallow around the areas I was fishing). My overhead had been broken off (snag) so I stopped fishing with that as well, because I really couldn't be bothered to re rig for the fifth (or more) time. I decided to drop my heavier line straight down on top of a ledge too - I knew there would be some cod in there and my assumption proved to be correct. After the other two that had been on the bridge left (their only notably catch was a small grassy), I had I the bridge to myself. I casted my lure numerous times, and was overly cautious when I saw something large and brown come out from the depth as I thought it was a bird that had gone swimming for fish. "Why oh why didn't I pay attention and realise the diving bird was on the other side of the bridge!" I thought to myself - Because I think what came up and had a go at my lure was that big cod from before!
Two others rocked up on the bridge at around 11:30AM (a bloke and his girlfriend, maybe 19), so I figured I wouldn't hassle them too much. The lure had proven fruitless so I checked my bait rod. To my surprise, it had a small cod on it. I managed to use the remainder of the dead bait winching in small cod, which would hit hard but give up too easy (3 or 4). 

Cod
At around 12PM I packed up my gear, and called my last fishing session in Yeppoon quits. Although I didn't catch anything worth telling my Grandma, I was still happy with the session. 
Quick Stats:
Tide: 5:35AM, 3.7M, High (tide would've just made it over the into the lake), 12:20PM, 1.5M, Low. Tide was only running from about 5:30AM-6:15AM, from what I found.

Abu Garcia Veritas on Diawa Shinobi 2500, Shimano Stradic 3000 on Shimano Raider, Shimano Aero on Rogue Firepoint Boat Rod (this combo caught all the cod).
Fish Caught: About 10 undersize/little cod/fingermark/bream/wrasse
Other
Anyways, apart from those 9 fishing sessions (9 in 5 days, not too shabby), we did a few other things. The Bluff Rock walk (2.3KM's or thereabouts, a nice and easy walk) was fun, and there were a couple of great viewpoints/lookouts. I beat my Dad in pool for the first time ever (proud moment 🤣), and the Fingermark was deep fried and tasted delicious. I think I ate about 15 prawns and 6 big pieces of fish! The drive on the way home felt a lot quicker but it still ended up taking the same time, 9.5 hours (possibly because of a longer stop to get lunch). I had a great time - and I figure it was a great way to spend some of my school holidays.
Thanks heaps for reading this report, I hope you enjoyed.
Cheers Hamish

If its a traditional transducer without side scan, then it's shooting out a cone shaped signal, and the size of the cone depends on the frequency that you're running. As you can see in the image below, the depth displayed is never the actual depth below the boat, but the shortest distance between the transducer and the first return signal.
You will never get the transducer installed exactly plumb as the pitch of the hull varies depending on the boat speed, and roll changes depending on how the boat is loaded on the day. You're over thinking it. Just install the transducer pointing down when the boat is on the trailer. As long as its not out by 5 degrees or more, you are going to get decent readings.
