The small underwater motors can replace existing combusting engines from 12hp to 25hp. These motors have a very high torque at very low rpm's, which means that it's possible to install a bigger propeller and get a much better efficiancy of the propulsion system. The motors are 3-phase AC motors and no gearbox is needed, which again means free of extra power losses in the gear and transmission system.
Converting to electrical propulsion will give a silent cruise, without smell and diesel fuel in the water. This green power system fulfil the expectations of protecting the sensitive environment in harbours, lakes, recreational areas for fishing and bird-watching, inland waterways. The motors can be installed into mono and multi hull sailboats and motor boats.
