I remember about a year ago seeing articles on repowering. A loose rule of thumb is 1.5Hp per ton of boat,of course that rule goes out the window with individual preferences and local conditions somewhat like a 50 hp on a 26 mcgreggor ( sailboat?)anyway a local dealer was selling new yanmar 27hp for about four grand plus installation,I guess bottom
line here is it won''t cost but a few phone calls for other price quotes,don''t commit to the big bucks unless you are forced to make it happen you know March 30 2005 wind blowing and 65 degrees throws reason out the window. Best wishes maybe santa will put one under the tree.
