Hey Guys,
So i have a PCM 5.8 HO and have had some issues with it. Most have been fuel problems, which replacing both the pumps have fixed. Now I am stumped. Basically the motor wont run past 2500 rpms. Taking off it struggles to get up on plane and backfires a few times. Once given power, and ran at WOT, it wont go past 2500 rpms or like 15 MPH. The boat has always been babied, only fresh water, and about 300 hrs on it.
