Dampner Plates & Couplers

Marine heavy duty engine flex plates are designed to take the punishment you dish out time and time again.

These all new Keith Eickert billet aluminum flywheels are manufactured from certified billet material that will not break up under the stress and severe punishment of on and off throttle in high RPM marine environments.

These flywheels have machined retaining recesses every 120 degrees attaching locating tabs that have been installed on the ring gear making rear gear shift and movement a thing of the past. By using a lighter aluminum flywheel you will be rewarded with both faster acceleration and deceleration. Giving you the edge you're looking for.

Standard duty - these plates contain dampner springs similar to a car clutch disc. These springs take the shock out of the shift. Not recommended for high performance applications.

Heavy duty - similar to the standard duty but designed to take the punishment of a high performance engine. Some machine work may be required to flywheel for rivet clearance.

This is a replacement engine coupler for the Mercury Hi Performance engine using a Bravo outdrive. This performance coupler is the best you can buy. Make sure your engine is aligned properly whenever installing a new coupler, failure to do so will greatly reduce lifespan.
