this is a pretty interesting motor http://www.plettenberg-motoren.com/UK/Motoren/aussen/Predator37/Motor.htm
1900 g and 15Kw ! The site says they can make special motors for marine use and with more cooling and bigger shafts. thats about 4 lb and 20ish HP. Light enough to be a hub motor, or to use two. whaddya think? John
