Sunchaser - - Yup I checked the tachs they are within 50 rpm. I mostly go out just to be on the water not going anywhere in particular. For me it's about the journey not the destination. So I just poke along and watch the scenery and traffic (freighters) go by.

I'll most likely go back to the original prop I'm not a big believer in over propping especially by 20%. Not sure why the PO went that much. Even if you gain 15% in fuel economy (which I doubt you do) with this engine at just below hull speed you burn < 1 gal per hr so your not saving much.

Thanks for you comments DonF
