🔌 Function
Secures the flywheel to the crankshaft flange, carrying the full drive torque through friction between the clamped faces and holding the flywheel true so the transmission or drive adapter runs without runout.
⚠️ Common Signs of Failure
- A heavy knock or rumble from the flywheel housing that changes with load
- Vibration through the boat that comes and goes as drive is taken up
- Bright fretting powder or rust bloom on the flywheel-to-crankshaft joint face
- Screws found slack, or holes in the flywheel elongated where it has moved
- Stretched shanks and pulled threads on removal, showing the screws have yielded
🛠️ Service Notes
- Confirm thread, length, grade and any single-use restriction against the exact application
- Clean the threads and use the specified torque, angle and locking method
