Hello,
New to the forum, i traded for a 16 foot Mirro craft, with a 1977 Johnson 75, i have been having problems with it..Motor startS right up n will accelerate n plain out n then start sputtering n losing power, if i throttle down it will come out some, n run rough.. I recently removed all 3 carbs n cleaned well.. I then went to check compression, compression ended up being top n bottom cylinder 150 psi n middle was 140 psi, well i found water on plugs, thinking possibly head gasket, any advice would be greatly appreciated..
