That is a good little engine, however it is 165HP at the flywheel. We figure that it puts about 150HP to the prop. As I understand it all of the newer engines rate the HP of the motor at the prop now. For us we would really like to have the 4.3L fuel injected Merc with 195HP at the prop. Have had several Merc guys tell us that the 4.3L being more efficient, burns about the same amount of fuel as the 165, producing the 30 more HP, allowing a Higher pitched prop and thus higher top end speed, getting you there sooner on the same fuel burn. At least it sounds good, and who doesn't like more HP.
