The present invention 10 discloses an underwater generator for use with a surface vessel 12 having a cylindrical housing 30 with two major parts: a turbine 32 and a generator 36. The turbine 32 is located in the front portion of the device and is connected to the generator 36 in the rear of the device through a set of gears 34. A conical shaped filter 24 pointed forward is located in the front of the turbine 32 to prevent clogging of the device. The size of the filter rib 25 openings is smaller than the spacing between the turbine blades so that any particulate matter that passes through the filter can freely pass through the turbine and out the housing. At the junction between the conical filter 24 and the main body of the housing 30, the water is deflected into the housing by a special deflector 28 thus forcing the water to pass through the turbine 32. A water flow passage 40 is provided for a water outlet and a leak proof enclosure 38 surrounds the turbine 32, gears 34 and generator 36. The housing 30 is connected to the vessel 12 by way of mounting frame 26.
