After doing some homework online we contacted Thunderstruck electric and ordered their brushless electric motor kit for sailboats.
The folks at thunderstruck were fantastic to deal with. They spent a lot of time explaining the system and what was best for our application. Their after sales service was first class and I was very impressed with this company.
The installation was very straightforward and went very smoothly.
Gary fabricated a custom motor mount out of half inch thick aluminum plate and mounted the motor to it at the top and two bearings at the bottom to prevent side loads on the drive-line.
A two to one gear ratio and idler was used along with a toothed drive belt.
