SigmaDrive HOW IT WORKS... SigmaDrive anti-noise and vibration solutions are available for virtually every type of craft with engines up to 1300hp, and beyond that output custom built units can be produced. Here are the units’ principal benefits. • High running speeds • A rticulation and plunging in a single unit • Low maintenance • S pace-saving installation solutions Even if an engine and propeller shaft are perfectly aligned when the vessel is built, maintaining that alignment when the engine is running and the vessel moving is an impossibility. However well the boat is built, that allows...

SigmaDrive PRODUCT SYSTEMS SD / V DRIVE The SD model fits shaft tapers and straight shafts and can be fitted to all makes of V drive transmissions. STS – Sigma thrust system This system incorporates a thrust bearing to isolate the propellers' thrust to the engine. It uses a combination of three SD units fitted together. Two of which are incorporated in the thrust bearing and another coupled to the transmission with an intermediate shaft. D-Sigma The D Sigma is a constant velocity joint for coupling up jet drives and sterndrives to the main engine.
