🔌 Function

The flexible coupling transfers engine torque to the propulsion shaft while damping combustion pulses, gear engagement shock and torsional vibration.

Common signs of failure:

• Knocking or rattling near the flywheel housing

• Excessive vibration at idle or under load

• Cracked or separated rubber elements

• Excessive rotational free play

• Drive engagement becomes harsh

• Rubber debris inside the coupling guard

• Propeller shaft does not rotate smoothly

• Repeated coupling-bolt loosening

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
