I have made a long drive leg for a lightweight proa that is being built in Tasmania. I built a llittle catamaran from ply to test its operation on Aura Vale Lake. Motor is rated 750W, being 48V brushless DC made for electric scooters. It includes a 7:1 planetary reduction. Input power is limited to 1000W for this application. The drive leg transmits power through a T10 toothed belt housed in a 50X50 square tube. The fairing and mounting are only temporary arrangements for this test.
