One of the most demanding marine applications for a propulsion system is waterjet propulsion. Both the engine and the jet drive are excited during use, causing tremendous strain on the shaft line and transmitting noise and vibration to the structure. The SigmaDrive D is a replacement Cardan drive coupled to a pair of constant velocity joints on the jet and propulsion system, they replace existing Cardan shaft for jet drives and pod drive propulsion systems offering significantly lower levels of noise & vibration. This application has been widely adopted on Law Enforcement boats and tenders for Mega-Yachts providing reliable and quiet performance in a range of operating conditions.
The SigmaDrive D series is available in the following models: SigmaDrive SDD D55, D100, D150, D250 and D300.
