Very frustrating, took the boat out for the first time over the weekend, and could not get on plane. The engine would not make over 3000 rpms. Idled for about 1/2 hour and then was barely able to plane. Boat hesitated for a while at speed, and then all seemed OK(?). I drove the boat for a couple hours with no probelms, and thinking I have bad gas and was trying to use it all (went from 3/4 to about 1/4 full). Anchored for a while, and same thing happened again, no power. Next day, again, no power but even worse. Well, I knew it wasn't going to fix itself. Any suggestions? We have to use gas with small % ethanol here in Northeast.
