Free boat for me - lots of questions
Divers may have a hard time finding much to tell you if there''s a lot of growth on the bottom. You may want to have them scrape it (if they will) and wiggle the rudder to make sure it''s not loose and about to surprise you by falling out. If you can post what kind of boat it is, people who know it may be aware of specific problem areas to check out. Engines vary according to how heavy the boat is and what your goals are.
J/24 racers squeak by with the lightest 3hp
motor they can find. To fight currents or head seas in or out of harbor, 6hp might be better on a J/24. On heavier boats, a lot of people use long-shaft 9.9hp motors. Be aware that because of the maximum hull speed, upping the hp quickly comes to a point of diminishing returns. Putting a 50hp motor on the back will make lots of waves and burn lots of fuel, but you won''t go much faster than with a more appropriately-sized motor.
