Yanmar 3YM30 in a PS 31 cruising RPM
I am reading and hearing different recommended cruising RPM on my Yanmar 3YM 30.
Maximum RPM from Yanmar is "3200-3600".
The dealer told me that my max RPM is 3200 (I guess for the specific boat and prop I am using).
So is my cruising RPM 75, 80, or 85% of 3200?
Again, dealer told me 75% of 3200, which is 2400 rpm, but I have read higher.
This seems a little slow, and the boat moves at 4.5-4.75 knots.
I would like to think I could run a little higher RPM, and a little better boat speed.
Any other opinions out there? Especially with the same hull and engine.
