I am back looking at installing an electric motor in the 36' steel sailboat I am building. 31' LWL, 10'6" Beam, 10 ton disp. I have a used Westerbeke 44B 40hp diesel but would rather not use it.
EBay has a 3201 gearbox but I was thinking it was too small.

Aaron,
The limitation is most often the continuous thrust rating of the bearing at the back of the motor, though torque and input rpm are issues too.
The 3301 is rated at 550 lbs of continuous thrust and the 3401 is rated at over 1,000.
The larger gearboxes can't spin as fast as the smaller gearboxes.
What is the torque of the motor, and the rpm where you are producing that much power?
We don't exceed 2,000 input rpm with the gearboxes we use on our units, and most often set the drive up at 1900 rpm.

Any idea what the max HP input is for the 3201 gearbox? What size gearbox would you for a 16 to 20 hp motor?
