Technical Specifications

Package Contents

• 1 x Propeller Drive Pin (Replaces 307949/765545)

Note: It is highly recommended to keep several spare pins on your vessel. Some vendors may offer multi-packs.

Installation Guide

1. Safety First: Ensure the outboard engine is completely turned off and in neutral. Disconnect the spark plug leads to prevent accidental starting.
2. Access the Propeller: Secure the propeller so it cannot rotate. You may need to remove a cotter pin and propeller nut.
3. Remove the Old Pin: If a broken pin is present, drive out the remaining pieces from the propeller shaft.
4. Align the Propeller: Slide the propeller onto the shaft, aligning the pinhole on the propeller hub with the hole in the propeller shaft.
5. Install the New Pin: Insert the new shear pin through the aligned holes. It should be a snug, press-fit.
6. Secure the Assembly: Reinstall the propeller washer and nut. Tighten the nut and secure it with a new cotter pin, bending the ends to lock it in place.

Troubleshooting & FAQ

Q: How do I know if this drive pin will fit my Johnson/Evinrude engine?

A: This pin fits a wide range of Johnson/Evinrude models, primarily 10-25 HP 2-strokes from 1968-1979, but also other specific models listed in our compatibility table. Always cross-reference your engine's model, year, and OEM part number (307949 or 765545) with our tables to ensure a correct fit.

Q: What is the purpose of a drive pin or shear pin?

A: The drive pin is a sacrificial part designed to protect your engine. If your propeller strikes an underwater object like a rock or log, the pin shears off. This action disconnects the propeller from the drivetrain, preventing costly damage to your gearcase and internal engine components.

Q: How often should I replace my shear pin?

A: Replace the pin immediately if it breaks or shears. It is also best practice to inspect the pin for signs of fatigue, corrosion, or wear during regular maintenance. We strongly recommend keeping several spares on board at all times, as a broken pin will disable your propulsion.
