  1. Suzuki Outboard Seajay Nomad Problem

    in Boating

    Posted

    So I raised the motor up 25mm put my grandson and 40ltrs of water as ballast up front ( about 65kg total)  and off we went. Got up to 33kph and was reasonable at getting out of the hole. Thought all good job done

    Today put my 100kg mate up the front and it struggled to get on the plane, so off with the 12”  put the 10” prop on and it would get onto the plane but it was slow 

    Not sure where to go to from maybe a hydrofoil 

    still have to take it to the weighbridge - so I’ll maybe do that tomorrow

    Any suggestions most welcome

    cheers

    Sorry for delay in reply to posts

    i still haven’t been able to get back on the water to test but will do so in a couple of days 

    Going to do

    take the boat to a weighbridge fully laden and see just how much weight I have added

    raise the motor up 25 mm and test then raise it up 50 mm and test 

    change the prop to 10” and run at standard height then 25and 50mm 

    On my first run I tried different tilt settings and shifted weight around 

    tilt made very little difference , with someone sittting on the bow I got an extra 4kph 

    i don’t know what rpm I am doing not sure how to read that without a tachometer

    yes its a new motor 

    i realise a 2 stroke 15hp probably has a different powerband than the 4 stoke but I had direct comparison with another tinnie same size running a 20hp Suzuki with I’m sure a 12” prop up in the Kimberley and it was faster than the 15

    i report my findings ASAP in the meantime any suggestion welcome

    cheers

    I’ve got a Seajay Nomad HS 3.7 and had a Suzuki 15 2 stroke on it with 2 plus gear on board it would get up and go with a top speed of around 30kph 

    i decided to add a floor to the boat and upgrade the transom to a LS and get a 20hp 4 stroke to compensate for the extra weight of the floor and some other bits and pieces all up about 50 kg extra including the motor 

    Problem is now the best I can get out of it is 15kph flat chat 

    the motor could come up about 25mm or so and it is running a 9 1/4 x 12 standard prop I have a 9 1/4 x 10 that I could try but not sure if I need to go down or up 

    any advice much appreciated

    cheers
