It was leaking from the floats, the throttle body, etc. I spoke to the shop today, and they can get it to continuously run at 3000 rpm and above, but as soon as they try to adjust it down, the boat dies. They're going to run a compression test on it, and are also wondering if a valve may be stuck open, and although I know engine basics, I'm just not sure where to go from here. Are there any solid boat techs here on the forums that could maybe point me in the right direction? Thanks.
