Re: Jon Boat Trolling Motor Help!
For a 12' boat, get the smallest motor. I wouldn't expect that you would need a 24v motor, then you need two batterys which adds that much more weight and takes up that much more room.
Here on I-Boats they have a selection of motors to choose from, but also check out places like walmart and local marina, price will vary as will the selection.
I've for a 14' with a 30 lb (transom not bow mounted) and in speed 1 forward its all I need. If your bow doesn't have a location, some treated plywood and self taping screws. All depends on your budget and how good you want things to look.
