Took the boat out yesterday, started it up and ran across the lake with no issues except a bit of surging on its way up to WOT. Once it got there, ran great. On the other side of the lake, I idled around for a bit then when I went to throttle up again and it bogged down and died. I could idle up in neutral bet every time I put load on it bogged and died. I was finally able to ease the throttle up and get cylinders 1 and 2 to run enough to limp home (other 4 not firing). If I tried to throttle too high it bogged and died again. Halfway across the lake while limping I tried a little more gas and all of a sudden the other cylinders kicked in one at a time and started running great again. Once they all started running, I could keep going but if I throttle down to idle and throttle up again same issue, I would have to bably it through the lower end of the throttle until all cylinders would catch. It seemed to get better the more I ran it through idle to full throttle cycles.
I am thinking it is a carb issue but really am trying not to have to rip the carbs apart. I rebuilt them last year and went out several times with no issues. Fogged them for the winter and now this. Could the fogging oil have gummed up the system? No tach so cannot give specific rpms. Tried adjusting air screws with no results. Couldn't pull and check plugs while on the water. Left tank as low as possible for winter and drained even further before topping off with fresh gas this year. Maybe bad gas??? bad carbs???
Thanks,
