Hunter 42 Wilmington, NC
I have a Yanmar 4JH2-HTE engine as the auxiliary on my Hunter Passage 42. Is anyone familiar with that engine knowledgeable as to the cruising rpm? I think it's 2100 rpm, but I'm not sure.

Thanks.

Normal cruising rpm is 70-80% of the max rated RPM.

If your max rpm is 3600 then you should be cruising at 2500-2900.

Look on top of the engine for a plate that indicates max rpm and continuous rpm. You can run at continuous all the time and Yanmar recommends this.
