The Suredrive™ Solution |
|
The
relatively short spline on the transmission input shaft, coupled with
the spline in the drive plate, is the weakest link in your boat’s
drive system. This spline arrangement is highly intolerant to poor
alignment and is very susceptible to wear from constant changes in
engine output (e.g. commercial fishboats operating at low RPM), vibration
and inconsistent off-on loading conditions.
The
Coast Guard uses Suredrive™ The Suredrive™ is designed to eliminate this weak link by locking a female center spline hub onto your existing transmission input shaft. It is not necessary to replace your input shaft even if the spline is worn. The Suredrive™ center spline hub will lock onto even the most worn spline surfaces. Durable elastomers (rubber inserts) are installed at the perimeter of the inner spider drive to aid in dampening engine vibration and torsional forces, thereby providing a much quieter drive system. Finally, the outer spider drive is bolted onto the engine flywheel. The center sockets of the outer spider engage the inner spider drive with the rubber inserts effectively cushioning the mating surfaces.
