Had compression checked all read around 95, replaced bulb and exterier gas line, had all 3 carbs rebuilt, cleaned tanks, cycled sea foam through 2 tanks of gas, new fuel filter, cleaned canister filter, replaced both fuel pump diaphrams, motor stalls when i floor it to get on plane eventually after numerous attempts it does plane and is steady puurs like a kitten with noticeable loss of rpm for as much throttle thats given, if i bump the choke button while running it gives me a sudden surge of power, both plugs on #2 b8hs ngk plugs wet foul, I notice more cyliders wet fouling after last check, the water impeller is new but the sensors beep once, then again after ignition, the indicator lights go out after second beep. It used to have a zinc anode just noticed it vanished today. I dont want to give up on this potentially great motor. Can anyone help?
