Grin's marine motor uses the same stator and side cover assembly as our famous All Axle ebike hub, but features high RPM windings and a special axle for direct coupling to a 1" propeller shaft. It is intended primarily for replacing ~6-10 hp diesel engines on 24-29 foot sailboats that have a straight shaft through a stern tube.    

This 20 rpm/V model with a 27mm wide stator is will suited to drive propeller shafts up to 1000 rpm with a 48V battery bank, or 1500 rpm shafts with a 48V pack.  We recommend a brushless motor controller capable of at least 100 continuous phase amps, such as the ASI BAC2000. 

This motor is in early beta release phase to specially selected people who have signed up for our Marine project newsletter.  

See the Grin Marine Kit Info Page for more details.
