Looking for some advice on what route to take with my 2001 Yamaha 2 stroke (70 hp). I have gone through the entire fuel system thinking that was the problem. Same problem persists, stalling under load /no idle. Then I cleaned my carbs out, problem continues. I just decided to run a compression check and after pulling the plugs, it appeared they had water on them (cylinder 2 and 3). Compression in cylinder 1= 100 2=60-70 (bouncing around/not holding pressure) 3= 110.
Wondering what direction I should go in now. Pull the head and install a new head gasket (maybe the water is coming n due to bad gasket). Could the compression being low and water being present mean the gasket is bad?
What can or should I do to test this? Really hope I'm not looking at a total rebuild...
