Ericson 28; Is 10 hp O.K.?
I have a 24'' 1964 Grand Banks Sailboat. An old HEAVY "wood" beauty. Against many folks suggestions (4 to 6 max), I put an 8HP on her. Turns out, I''m glad I did. Yes, it is heavy to yank up the motor mount while out on a rough sea but that extra power has been a plus. I can only turn it up to 2/3 power and even at a tad above half speed it pulls the mount and motor way down into the water. I just have to move all the weight forward. Even still, the extra strength has been worth while since she''s so heavy.
An Ericson will be considerably lighter though. 10HP may be just too much. Don''t expect to successfully wrestle with it if it dies at sea. It will be VERY heavy when it''s wavey. You''ll never kick the throttle past 2/3 the way either. If the motor is free or cheap, use it. If you are buying it new, I suggest a couple horses less.
