DriveGuardian NXT is a patented device that improves the reliability of your NXT transmissions and drives. DriveGuardian reduces the torque spikes that are created each time the propeller becomes aerated or exits, and then re-enters the water after hitting a wave. These spikes are generated by the inertia of the rotating engine components and have been measured to be 2X-4X the actual torque output of the engine. These torque spikes far exceed the manufacturer’s torque rating for the NXT transmission and drive, which can lead to broken gears and twisted shafts. DriveGuardian is a torque-limiting clutch that absorbs the damaging torque spikes and protects your entire drivetrain. DriveGuardian has been proven on the racecourse with numerous National and World Championships in offshore powerboat racing.
Prior to shipment, each DriveGuardian is mounted to a specially built dyno and load tested to ensure they meet strict manufacturing standards. Your DriveGuardian is then calibrated for your specific engine and drive combination.
DriveGuardian is manufactured using billet aluminum housings and Kevlar clutch plates. The clutch plates are replaceable and the typical rebuild interval for an offshore performance application is 500-600 hours. DriveGuardian NXT retains the OEM damper plate and is a direct bolt-on with no additional modifications required. Includes a 1-year Manufacturer Warranty.
