Overview
Flexible disc transmission couplings provide a damper between the gearbox and propeller shaft to isolate torsional vibration from the engine and gearbox. They also reduce the shock of forward and reverse gear changes. These couplings work in conjunction with the engine mounts, providing the softest element in the drive train assembly for reducing damaging shock loads. Poly Flex couplings are manufactured from high strength polymers that are resistant to fuels and oils. They also serve to electrically isolate the engine/transmission from the propeller and shaft. Every coupling comes with easily followed installation instructions.

• Poly Flex uses a color coding system to visually identify the hardness of each coupling
• Green = 80 Shore Durometer Hardness(SDH) - 'A scale'; Red = 90 SDH-A; Blue = 95 SDH-A
• Please call for ordering and sizing information
