Re: Repower confusion (horsepower)


Our boat's got very similar specs as far as LOA/LWL/DISP go, and has a Perky 4.108M installed.

Although the 4.108's rated at 50 hp, that's at max rated RPM (4k) WOT when the stars and planets are precisely aligned; in practical terms we typically run it in the 2200-2400 rpm range for cruising, and with a spanking freshly cleaned hull in dead flat conditions we can go at hull speed (three bladed 16-10 prop). While my memory is fuzzy, I think at those rev's we're looking at around 30 hp output.
