Total Protection for your drive train.
Absorbs vibration, reducing noise.
THE DRIVESAVER provides a flexible, non-metallic barrier between your transmission and shaft. This barrier reduces not only drive train vibration, but the transmission of vibration and noise to you, your crew and the water. Both you and your vessel are more efficient in this quieter environment
Absorbs shock.
THE DRIVESAVER effectively absorbs thrust and torque from the propeller shaft, as well as excessive shock from changing gears and high speed planing. It also helps control damage and misalignment from torsional engine movement. And THE DRIVESAVER keeps on working, under normal conditions, for the life of the drive train, with no lubrication or maintenance.
Prevents electrolysis.
THE DRIVESAVER provides an impervious barrier that blocks electrical currents from the water. Your engine and transmission are protected from damaging corrosion.
Acts as a circuit breaker.
Repeat users of THE DRIVESAVER install new ones not because an old one wore out, but because of a hidden log, line, or rock that destroyed the coupling. That's right, THE DRIVESAVER was destroyed, not the costly transmission and engine. By acting like a circuit breaker, THE DRIVESAVER absorbs the extreme shock and torque of collision, breaks apart, and leaves your transmission and engine intact. You're back in operation faster, at a minimum cost. That's the kind of total protection you can't afford to be without!
Installs easily.
THE DRIVESAVER installs simply and quickly. Without cutting or machining the shaft. And without hauling your boat out of the water. Just separate the drive flanges, insert the coupling, align and bolt.
