Have seen several used by club members at IWA rallies.
Personally am daunted by the effort in transferring a big battery.
Will do some homework and feed back.
Aye, had a MinnKota 46lb thrust which was great for the 12-17ft grp resevoir fishing boats I have used it on usually get 8-12 hrs use from a 110ah deep cycle batt, but definatly not recommended for an inflatable dinghy, just not able to push it along like a petrol motor can.

I've got a Yamaha model which gives about 2hp output.
Use it on a Tehri Baby Fun hard dinghy to get out to my mooring. The Tohatsu 3.5 hp lives on board. The electric motor is so much lighter and does not stink the car out on the way to the boat. The 12 volt, 24 amp hour battery is good for at least three return trips or about 30 minutes at medium revs and is again easy to carry in it's canvas bag.
batteries are the problem. I had a couple of 26ah packs which ran the 30A motor for about 1/2 hour each and were managable but still heavy. In the inflatable i could get fast rowing speed and even limited movement when towing the bigger (7m) boat.
If you have the money then the lithium ion pack outboards look great.
Great in the shallows as you can run the engine with just the lower half of the prop in the water for a 3" draft.
Lots of use on the rubber dinghy, and the boy can play in it for hours with no noise and little cost.
It has pushed a 14"rowing boat and canadian canoes round the lake.
I used it on our 20" Catamaran as the main motor but had the petrol as backup for high winds, tides and anything over a mile.
I use it as the back up on our 26" catamaran in the marina just in case the engine fails. Nice to have a little controll of our destiny.
I intend to mount it on the front of the cat to use as a bow thruster.
bad points are limited range, I will buy a small petrol outboard for the dinghy to explore rivers etc.
I have been building a 11' dinghy and I have an electric out board to push it along, a Rhino 54. I have modified the design of the middle area creating 2 watertight battery banks in which I can fit 2 batteries in each. The curcuits can be switched easily using a battery switch and the lines I have run give me power points for other items such as lighting and I have even thought about electric bilge pumps! /forums/images/graemlins/laugh.gif
I have 2 60Ah batteries and once I start using her this summer I will let you know how I get on for durability /forums/images/graemlins/wink.gif
We've got a Torqeedo T800 - that's the sort with the Lithium-Ion battery - and we use it to power the tender. It really is as powerful as a 2hp petrol outboard, but quieter and no fumes. The battery is quite dinky - but the one drawback is that it only lasts about an hour of continuous bimbling (e.g up a river). We have never wanted to carry petrol on board (gas is bad enough when it comes to having explosive things).
