Diesel Max Continious RPM
Hi folks
Now I am getting used to things a question for diesel owners.Love the fule consumption but still a lot to learn about the engines.
What do people run their engines at (RPM) for long periods
The engine is the Yanmar 4LHA-STZP
My engine has a max continous rating of 190HP, but they then give two curves for power, crank and propellor output.
Crank shows 190HP at about 2300RPM, and propellor shows 190 at about 3100RPM.
Based on this and what other people run, what is the max RPM I can hold for long peopds,say hours, is it 2300RPM or 3100RPM, or somthing different.
While it is nice to run fast when conditions allow I dont want to damage the engine in doing this.
Also at max RPM 3300RPM and a Bravo 3X on 15.5" * 25" props I am getting about 32-34KTS does this sound about right?.
Regards Gary
