Re: Engine programming

No, the top rpm is only limited by the rev limiter (6400?) which cannot be changed.
A higher pitch prop will drop rpm.
Only getting to 5300 with a 22 pitch prop would be "overpropped" and should have gone down to a 20 pitch to bring the rpm up.

Re: Engine programming

I get that. I have owned a few. My curiosity is to why trimming the prop up to the surface the engine does not rev past 5300. Even as mph is decreasing. Spec for the boat props it with 23” and 24”

give us all the info about your engine, prop details, types of gauges, boat make and model, top speed and rpm.
