Here are some photos of the 10 KW Electroprop electric drive conversion I'm doing now on a 40 foot ketch weighing an estimated 10 tons.
Note the beautiful 4 bladed, 14 inch diameter, 20 inch pitch propeller!
This boat is going Lithium with Sinopoly 300 amp hour batteries on a 72 volt system.
The motor is a Perm 156W at 92.9 percent peak efficiency.
The yellow plugs on the bottom of the motor are for water cooling.
