I have a 1994 Four Winns with a 5.0 EFI OMC(Ford) Cobra Engine. The boat starts fine and runs well in neutral, even up to 5000 RPM. When I put the boat in to gear and attempt to take it to WOT the engine will not exceed 2500 RPM and is getting no power to get it up on plane. There is minor backfire if I open the throttle up all of the way. It seems to me like a fuel problem but I have checked most points of the fuel system. I have been replacing parts and spending way too much money to keep guessing at the problem. Gas pressure is ok at WOT. I have done the following:
Replaced the fuel pump
Blown out the fuel lines
Replaced the alternator
replaced starter relay
checked fuel pressure
I have been told that the issue could be in the timing, so I removed the distributor to replace the pick up coil. Have not been able to disassemble the distributor(maybe another post), but their is minor corrosion on the old coil. Could that be the problem. If that does not fix it I plan on opening up the engine to adjust the timing chain. Has anyone experienced similar problems. Please HELP!! I can feel the minutes of the summer slowly sweating away as I sit in this greasy hole.
