I think if I was wanting to be cheap and durable, I would look at a couple Swamp cooler pulley sets. They are about 20:1, and with a pair, and a short jack shaft and the same self aligning bearings, you would see at least 40:1 and would be out less than about $30. Barring that I have seen a lot of 60:1, and 90:1 gear boxes with motors attached and in about every voltage out there, being sold on eBay. I bought a pair for steering motors.

Subject: [Electric Boats] Electric paddlewheel
We're in the midst of designing a small electric paddlewheel boat, and would love some feedback. The vessel as designed would be a flat bottomed (barge type hull) 7 beam by 20' long excursion boat (obviously ne'er intended to plane) We're looking for a motor/controller kit to power it. For those not paddle-initiated, the wheel should turn at no more than about 60rpm, so there's quite a bit of down-gearing from the motor. Ideas? Product source suggestions? Our first one of these ran off a winch motor, but the duty cycle of those proved impractically short.
