I would go with the stock motor before dropping down to a 23 turn motor. The stock motor should be a 27 turn motor. I run the stock motor with either a 4 to 1 reduction or 3 to 1 with absolutely no problem with the MFU.

A high turn motor that has lots of torque will work well.i tried an 85 turn motor,it wouldn't even move so i went to the 55 turn motor and its great and with our club truck i think i put a 55 turn in.that and locked it in first gear..its slow and has torque.the 55 turn will work with your mfu
