Hey All, I need some advice on where to look next. I have an 04 280 DA. Twin 4.3 MPI. Alpha drives. My port engine is only getting up to about 3000 RPM at wide-open throttle when trying to get on the plane. As I move the throttle forward and back a little, it surges and varies. The starboard engine at full throttle at full throttle is running about 4000 RPM. I was hoping it was distributor cap related so I replaced the cap and rotor but that did not help. Fuel filter has been replaced and no avail either.
once it finally gets up on plane I can cruise both engines around 3500 RPM with no problem and they sound fine. Both engines idle perfect and start right up. Not sure what I should try next. Any advice would be appreciated.
