A one-piece steel driver for your motor, to connect to the propshaft thru a square-ended flexshaft. This driver attaches to the tapered output shaft by means of a short, threaded steel insert. It actually tightens as you run the boat, no locking compound needed.
While we don't manufacture this driver, we feel that it is the best one to use with our drive. The steel construction means it will last a long time, even under hard use.
