One-piece coupler for the SE80, SE100 thrusters.
On older SP75 and SP95 models, you can replace just the rubber Lovejoy coupler #SM71451 or you can replace the entire 3-piece Lovejoy coupler with this 1-piece coupler
On older SP75 and SP95 models, the SM71453 driveshaft flange is no longer available for individual purchase so this 1-piece coupler would need to be purchased.
