I've searched everywhere for a similar issue, and have tried every suggested fix so far and I'm still at a standstill.
Here's the back story.
I've got a 2003 Sundancer 260 with a 6.2 MPI and bravo III. Last season, she was running perfect, until one day she just lost power in the middle of the river and slowed down until the motor completely stalled. It ran like crap until I replaced the fuel filter, then all was well for the remainder of the season. This year, I take her out and it takes a little longer than usual to get on plane. It had been sitting through the winter, so I figured it may just have some old gas or **** on plugs or something. This symptom has become progressively worse. The boat now won't get on plane or rev over 3000 RPMs unless I am on the boat by myself. Even then, it still has trouble getting up. When I'm in neutral revving the motor, it sounds great! It's not until I put a load on it and try to get up on top of the water that it starts to crap out on me.
So far, I've replaced the fuel filter and water/fuel filter. Checked fuel pressure, and its consistently right above 40 PSI under all conditions. I've changed air filter, spark plugs, and distributor cap and rotor, and it is still giving me trouble. I'm not quite sure where to turn, and I don't have a diagnostic tool to read engine computer data. I will say this, it does seem like it is choking out a little if you give it more throttle. Almost like it is running lean or rich.
In addition, I've run the boat with the engine hatch open to bring it fresh air in the instance exhaust manifolds were leaking. Didn't make a difference.
help would be much appreciated!
