I have often wondered how well they work and how good of a replacement they would make for a saildrive. I have a 26ft boat with a 15hp saildrive and primarily day sail with an occasional weekend cruise. I am not having trouble with my saildrive right now, but the day will come when I need to repower. I like the idea of an electric drive, quiet & clean power, but would be hesistant to go that route right now. I would be interested in hearing about the experiences of anyone who did go that route.
