Santa Barbara Marine Diesel Mechanic. can install a large array of Marine flexible shaft couplings on your Yacht or Sailboat. by fitting a flexible coupling between the gearbox and the propeller shaft, annoying vibrations in the boat are largely eliminated.
A flexible coupling ensures the diminishing of vibrations and noise to a great extent. The average noise reduction amounts to about 5 dBa, or up to 30%.
Misalignment of the propeller shaft can also be compensated, with the result that gearbox and shaft bearing are less subjected to wear and tear.

Designed for smaller stern gear installations, the flexible rubber element of the Bullflex flexible coupling ensures low-noise vibration-free transmission, without backlash between the engine and the propeller shaft.
A special centering ring allows high shaft revolutions, and even in reverse gear, the shaft will remain perfectly centered.
• Optimum damping of vibrations
• Non-tapered clamping hub ensures easy installation and disassembly
• Misalignment of up to 2° permissible (misalignment restricts max. engine RPM, however)
• Secured against shearing off, axially and radially
• Eliminates propeller shaft backlash
• Special adapter flanges for Volvo, Yanmar and Kanzaki are available as options
Bruntons SigmaDrive is a brand new 21st Century solution that is already an award winner and provides effective anti-noise and anti-vibration solutions of the highest order.
What makes SigmaDrives different is their 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 utilising the space available ergonomically.
SigmaDrives are designed to fit virtually all boats from yachts to workboats, canal narrow boats to military vessels; in fact pretty much any powered vessel with engines up to 1300hp. They are extremely easy to fit, requiring no modifications to the craft, which can usually be equipped with the drive unit whilst still in the water.
Together with its anti-noise and vibration abilities having a SigmaDrive on your vessel also ensures that seals and bearings are always perfectly aligned, reducing wear and guaranteeing a longer trouble-free life for all associated components.
Description
The Bullflex coupling has been especially designed to ensure optimum damping of vibrations.
Torsional vibrations which are due to cycle irregularities (especially at low revs) are smoothed out extremely efficiently, thanks to its very flexible rubber element.
This pre-tensioned rubber element ensures low-noise and vibration-free transmission, without backlash between the engine and the propeller shaft. is secured against shearing off, both axially and radially, thus ensuring safe transmission under all circumstances
4-3/4″ Drivesaver Flexible Coupling for Twin Disc and ZF marine Transmissions by Globe Composites (4756)
Reduces vibration and provides a flexible non-metallic barrier between your transmission and propeller shaft. It absorbs extreme shock and torque caused by impact with logs, rocks and line. Drivesaver with stands oil, sludge, saltwater and temperatures of -65F to +225F.
All metal components and hardware are plated for corrosion resistance and long life. Servicing: Oxnard, Channel Islands Harbor, Ventura Harbor, and Santa Barbara
