Follow the engine operations manual! The
motor doesn’t know if it’s installed in a FP or a
Beneteau. There is nothing special about the
hull that restricts “normal” engine operations. I have the same
motor and usually run 2400 - 2800 depending on my needs/desires.
(Sorry… I’m not a
mechanic. If you’re still concerned, go join Boatdiesel.com. Lots of support and
advice from some respected mechanics. Even then, you’re only getting the
advice of someone on the
internet. Even me! Which is why I say default to what the engine manufacturer tells you.)
