Good To Know

Q: What is the purpose of a shear pin? A: It is designed to break when the propeller hits an obstruction, absorbing the impact and protecting the drive train from expensive damage.

Q: How do I know when to replace the shear pin? A: If the propeller spins freely but the engine revs without moving the boat, the pin is likely broken and should be replaced immediately.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
