Got the boat out today and it ran with poor power. Back to the drawing board.

I took the fuel pump apart to clean it and did notice a very small tear in the diaphragm so I think rebuilding the fuel pump is a good idea. I just bought the boat about 3 weeks ago and have had it out about five times and it starts fine and idles really good. The boat just won’t plane out. My biggest fear is seazing a piston. I’ll be taking it out tomorrow to see if my thorough carb and fuel line/filter clean works. I’ll keep you posted. I only run non ethanol gas and my gas won’t sit for long until winter. Wish me luck.

Anyone else have this issue? I’ve checked compression, spark, fuel pump, fuel filter, cleaned the carb, checked for hub spin. I’ll be taking it out tomorrow for a spin to see how the afore mentioned works. My next step will be pulling the flywheel to check the stator and magnets, piston rings. my next option would be to check the reeds…don’t really want to go there but…

I know it’s been 3 years since the last post but I’m wondering if you resolved this issue. I’m having the same problem with my ’88 35hp merc.
