Hi everyone.
Hoping some of the resident experts can help me track down an issue I started noticing after I installed my FAE. I've since removed the FAE and the problem persists. My 22ve is equipped with the MarinePower 5.7. The symptoms occur after extended idle around 5 minutes or so. If you let it idle long enough, the idle will become rough and the RPMs will start dropping. Once this starts or even before but after a few minutes of idle, when you attempt to accelerate, the engine bogs down unable to accelerate. You will usually hear several afterfires as the engine tries to "clear" itself. Once it does, power is restored and the engine accelerates as expected. This is the only symptom I have found. You can stop and idle for a minute or so then accelerate with no issues. Top end seems fine and as long as you keep some load on the engine above idle, you can cruise at as low as 5mph forever without any issue.
This is an awful issue to have trying to teach new people how to surf as you tend to spend a few minutes between pulls talking to them, then when you go to pull them out of the water, you lose all power and they fail.
I have noticed that after a long idle, I can rev the motor in neutral just befofe pulling the rider out of the water and most time, the hesitation and afterfire will not occur.
My novice guess is that the fuel pressure might be too high causing the engine to run lean. At idle this could be causing the exhaust to load up with fuel and creating the afterfire and hesitation. Could a faulty fuel pressure regulator cause this? Am I barking up the wrong tree? Any insight would be greatly appreciated.
