BoatTechTV Episode 7 - SigmaDrive Shaft Coupling

Bruntons SigmaDrive is a brand new 21st Century solution that provides effective anti-noise and anti-vibration solutions of the highest order. What makes SigmaDrive different is it's ability to resist propeller thrust when installed as a standalone coupling, directly from the shaft to the output flange on the engine’s transmission. It reduces and even eliminates vibrations that originate from an imperfect alignment between the propeller shaft and the engine, compensating for up to 3 degrees in all directions. This system can also be installed using thrust bearings so that the engine can be placed utilizing the space available ergonomically. Episode 7 gives an overview of the SigmaDrive, how to fit it and how it works.
