Len,
The Torqeedo motors can easily be purchased from a variety of sources, including West Marine, Defender, and Jamestown Distributors.
Yes, they are a bit pricey. The Torqeedo 1003 is around $2000 and the Torqeedo 2 is around $3300-3500. Then there are batteries... You really should consider high quality, high amperage AGM batteries (if not Lithium - which will be even more expensive, but perhaps a reasonable tradeoff, depending on what you plan to do).
I've used both the Torqeedo 2 and 4 on a Catalina 22, and can tell you they're great motors. Lots of power, seem to be very reliable. The biggest downside is that they are really expensive. But you get a great solution that you just plug in to a battery and go.
Good luck!
John

Thanks for the info. The boat has a bare hull weight in CB version 0f 820 lbs. The keel version was 960 with a 320 lb keel so I figure the CB version has some ballast.
Since this hull was a keel and doesn't have a CB trunk I have some room to add ballast for stability.
I am at the opposite end of the country. South Central FL and would use it on two lakes Of maybe 5000 acres, that have ramps within a mile of house.
What would be the cost of either of the motors. Got a feeling they are going to be outside my price range since live on a fixed budget (SS)
GPS and computers seem overkill for this usage.
Here is the boat as I have it and as it was new

Capt. Len,Thought I would answer you note in the user forum.This is the data on the boat:Hull Type: Centerboard DinghyRig Type: Fractional SloopLOA: 18.00' / 5.49mLWL: 17.00' / 5.18mBeam: 6.25' / 1.91mDisp. 1050 lbs./ 476 kgs.This is a speed and power table that I modified for your light displacement:Speed & PowerKts Amps Watts1.9 4 1922.9 6 2883.9 10 4804.9 20 960 you will reach hull speed at about 1200 watts6.2 40 1920 You would see adequate reserve power with a 2kW motorHull speed 5.52I would recommend up to a 2.5hp outboard as being very adequate. In the electric world I see two choices for you:Torqeedo Travel 1003 adjustable shaft tiller is a robust, efficient electric outboard with built in Lithium battery pack. The 1003 has a high efficiency battery capacity, and an on-board-computer (including GPS and real-time range calculation). Torqeedo rates it as a 3 HP output but in a sailboat plying open ocean or lake, I would think it is more like a 1.5hp.Torqeedo's Cruise 2.0 long shaft remote control motor a robust, efficient electric outboard with a 24v battery pack in the boat. The Cruise 2.0 has an on-board-computer (including GPS and real-time range calculation). Torqeedo rates it as a 5 HP output but in a sailboat plying open ocean or lake, I would think it is more like a 3hp. Traditional batteries or Lithium batteries can be used on this motor so that you can position the batteries to the best effect in the boat.
Both Torqeedo outboard us a very efficient slow propeller that may have some deformity in a negative sea state but would likely be adequate for your light boat.
