bill: many P15s and M15s have made the crossing to catalina is. i have toured puget sound, the san juan islands and the gulf islands using a honda 2HP long shaft on an M15 and Sage 17. unless your current motor is failing, or cannot be used at your local sailing/cruising location(s), continue to use the motor. a 2HP long shaft motor is an excellent fit for the M15. i had not problems with my honda 2HP on my M15. about the only improvement for the honda 2HP would be an external tank option. a 4HP motor is significant overkill and adds un-needed weight on the transom of the M15. :: Dave Scobie :: former M15 owner - www.freewebs.com/m15-named-scred :: Sage Marine --- On Sun, 3/11/12, whinkeljr@cox.net <whinkeljr@cox.net> wrote:
I am intending to go with the SoCal Potters on one of their trips to Catalina, and also to tour the San Juans - all in my M15, "Prelude". Is a 4HP 4-stroke a good choice @ 59 lbs, or would a 3.5HP @ 43lbs be better? Right now I have a 2.5 HP 2-stroke, but that is progressively being banned everywhere. Thanks! Bill Hinkel M15 "Prelude"
