2008 Super Air 230 performance issue

[pekelly]

My super air 230 seems to have lost power and runs a little rough at idle this season. Always maintained well by me. No warning lights on. Starts fine but no power. Only tops out at 35 mph and poor accel compared to last season. Fuel filter has about 60 hours on it. Cylinders seem to not be miss firing. Poss fuel filter clog? Has 192 hours on boat.

Possible ethanol issue. Did the gas in tank contain ethanol and was it treated prior to storage?

Check your spark plugs if you have the 6.0 liter engine as the plugs are sensitive to fogging oil.

you do know that the boat has two fuel filters, right?

yes

Changed in line fuel filter and spark plugs. Runs great now! Any tips on changing the fuel cell filter? Looks like fun.
