Re: overpropped vs underpropped
Yanmar 4JH5E naturally aspirated.
I note that you say your engine is a Yanmar 4JH5E and that it has a governed rpm rate of 3,400rpm. May I ask where you got this data from? The only data I can find for it from Yanmar is a maximum output rating of 53mhp at the crankshaft at 3,000rpm I'm asking because I'm trying to find a source to find out what is the maximum WOT rpm of my 3JH5E engine.
