I have a 7.4 MPI in my boat and the current rev limiter or governor is set at 4200 RPM. I am wanting to turn the motor to 5000 RPM. Has any one done this and had any luck with it or have you had motor damage? I had the same motor in a tube chassis rockcrawler with the rev limiter adjusted by FastChips to 6500 RPM and the motor would set there and take it ALL DAY LONG with no problems. I know that the motor has a cast crank and cast pistons, but was just wanting some feed back on this since the boating thing is new to me. Any comments would be appreciated.
