NextWave Marine Systems Inc., is a progressive design and manufacturing company situated on Vancouver Island in British Columbia, Canada. NextWave was founded in 1997, building on years of knowledge and experience in heavy equipment and marine diesel propulsion systems. Our company has a strong practical engineering capability which has led the way to produce innovative products. SUREDRIVETM Our main product is a torsional marine coupling (Suredrivel) which is distributed world wide. The coupling has been successfully applied to marine, industrial and agricultural power transmitting systems with excellent results in both durability and performance. Many marine transmissions rely on a floating spline coupling arrangement to transfer power from the engine flywheel to the transmission. 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 SuredriveT is designed to eliminate this weak link by locking a female center spline hub onto your existing transmission input shaft.
