One-Piece Flexible Coupler - SE80 & SE100 Thrusters

This is a one-piece flexible shaft coupler for upgrading the original three-piece "Lovejoy" coupler on older SE80 and SE100 thrusters. It can be installed with the boat in the water.
This coupler is not only a more convenient design, but it also allows for a more precise failure point than the original rubber coupler – providing better protection for your thruster.

On older SP75 and SP95 models, you can replace just the rubber "Lovejoy" torsion sleeve (SM71451), or you can replace the entire 3-piece Lovejoy coupler (rubber torsion sleeve plus metal motor and gear leg coupler flanges) with this new SM71462 one-piece coupler.

On older SP75 and SP95 models, the SM71453 motor driveshaft flange is no longer available, so this one-piece coupler is your only choice if you shear the original rubber torsion sleeve.

Flexible couplers are designed to transmit torque (by connecting two shafts) while damping vibrations and accommodating minor misalignments, protecting the device from damage.
