    full throttle and no go?

    Lately I've been having problems with my 3cylinder 40hp yamaha. My friend adjusted the jets so the engine doesn't stall when I go full throttle. Now with that fixed, I can go full throttle, but now I it doesn't seem to go anywhere. I know the prop is spinning but it's not going.

    Need Help With My Yamaha!

    What I was told was that I have a 40hp Yamaha that's probably over 10 years old. That's all I know about it. First off, how can I find more information about my motor? Second, the motor was running fine until one day it just crapped out. I can't get past idle throttle without it stalling out.
