outboard issues

[kdavo]

hi there, just wondering if someone might have an idea as to whats happening with my outboard. Outboard is easy to start...however when outboard put into gear it just konks out, starts ok, then you put into gear and it just konks out again..it then vibrates ...however once you have pushed the gear up and down the power then kicks in...and no issue after that? just changed the plugs as well.

yamaha 70hp two stroke.

any ideas and help appreciated?

check your plug gap

[kdavo]

hi there, got the plugs from northside marine and they were gapped accordingly for the outboard. Problem was there before the new plugs put in too?

[noname]

have you played with mixture screws ???

[kdavo]

hi no-name, no..where are the mixture screws?

[mick2me]

maybe check you idle lever cable could be getting caught...

make it idle a bit faster when in neutral

Hi, had the same problem with my Yamaha 40hp. I had to get someone to remove carbi's and give them a clean out as due to being run with dirty fuel from previous owner there was a whole heap of crap floating around in the carbi's. These little bits of gunk would occasionaly block the fuel jets and hence the stalling when trying to idle. It cost me around $300 to get this fixed. My Yami is a 3 cylinder 2 stroke....It hasn'tissed a beat since...

Try

1) to locate the "in gear lock out switch". If there is enough play in the gear selection lever the motor might be "tripping" out thinking the boat is being started in gear.

2)Maybe the idle is to low.

3) had this one too, - check that the "kill" layard switch is not loose in the forward controls. Moving the gear lever moved the kills switch enough to activate.

Ideas to try - not saying it is the cause though!

Like ellicat said-try to get in contact with rum runner.

Other wise sounds like an idle adjustment. Or the fuel line is sucking a tiny bit of air through the fuel line.check the fuel line couplings.might have a split O ring?

I read on Rumrunner's Profile that he is in the GC hinterland. What areas does he work in?

[ellicat]

He's a Tamborine Man (play a song for me haha), but will travel at a cost.

Check the timing advance is working. My Johnno 70 idled fine but once in gear and try to accelerate it stalled. Timing advance was jammed.

that can happen when you have water in the fuel. idles fine then when put into gear konks out.
