I purchased 3 years ago a 1983 Hunter 27. It has the Yanmar 1gm
Rated at 6.5 HP at 3400 rpm. Max Rpm is rated 3600. I only get about 3000 rpm in forward gear and up to 3600 in neutral. In calm water I guess max speed no sails is 5.5 knots.
The prop I have is 2 blades 13 in dia
10 in pitch. Looking forcomments of other owners with this boat and engine. How is your power, Rpms and speed?
Thanks for all comments -
