David,
As an experiment, I tried using a MinnKota 24V Traxis 80 (80# Thrust) on my Catalina 22.
The motor would push the boat - up to a max of about 3.2mph into a moderate breeze (around 10-12mph).
The two issues I had with that motor were that 1) due to the low pitch of the prop, max speed still didn't get the boat speed I wanted, and 2) at full speed, the control head got hot to the touch within 30 min or so.
It sounds like it might do what you need. But if you bolt it to the hull, you'll have a LOT of drag when you're sailing. If you run the motor at slow speed, you could at least overcome most of the drag - though your boat would likely be able to sail faster than the motor can power it in a good breeze.
Good luck!
John

I'm thinking of fitting a Minn Kota 24 volt RT80EM Saltwater Motor (80 Lbs. Thrust) or something similar, bolted on the hull near the rudder of my 23 foot sailboat.... this propulsion is just to get the sailboat in and out of the creek, not more than 300 ft until I can pick up the wind. Speed is not an issue, but we do have maybe a one knot tide worst case. Does anyone have any experience of this kind of propulsion? Are there any alternatives out there for hull mounted electric propulsion units? I don't want anything hanging over the transom. Thanks... David
