Re: [macgregor19sailboats] Re: Motor replacement
- The other aspect is prop choice. A prop can get you up on plane faster vs. a higher top speed. Also angle of the motor and possible use of a planing plate on the outboard or adjustable angle planes on the transom like some power boats use to keep the bow down and get up on plane faster. Lots of choices/decisions.

I agree with Mike, when I have to repower I will be going up to a 50. I don't think a 30 hp or less will get you on plane. Maybe a 35 if you are lightly loaded and the load is distributed well, at least 80% on the v berth. When powering we will gain almost 2 mph (gps) when my wife (135 lbs.) moves from the cockpit and goes below and sits on the edge of the v berth. The only thing I can offer is if you stick with a 40 try to get the lightest model available as they can range from around 200 to almost 300lbs.

Â Add the passengers, gas and all the gear and a non ideal prop and you can barely get it to plane with a 40 hp. Â
