Installation Guide
Always consult your service manual before performing maintenance. The general steps for replacing a shear pin are:
-
Shift the outboard motor into the NEUTRAL position. For safety, disconnect the spark plug wires.
-
Remove the cotter pin from the propeller nut using pliers.
- Unscrew the propeller castle nut and remove the thrust washer.
- Carefully slide the propeller straight off the propeller shaft.
- If the old pin is sheared, remove both pieces from the propeller hub and driveshaft.
- Align the pin hole on the new propeller with the hole on the driveshaft.
-
Insert the new drive pin through the propeller hub and shaft until it is centered.
- Re-install the thrust washer and tighten the castle nut.
- Insert a new cotter pin through the castle nut and shaft, bending the ends to lock it in place.
Troubleshooting & FAQ
Q: How do I confirm this pin fits my Johnson/Evinrude engine?
A: First, verify your engine's horsepower and model year fall within the 10-25 HP range for 1968-1979. Then, check the Compatible Engine Models table on this page. This pin directly replaces OEM part numbers 307949 and 765545.
Q: What are the signs of a failed or sheared drive pin?
A: The most common symptom is a sudden loss of propulsion where the engine will rev freely, but the propeller does not spin. This indicates the pin has sheared, which occurs after an impact with an underwater object and is designed to protect your engine's gearbox from damage.
Q: What is the difference between this pin and the original OEM one?
Our aftermarket pins are manufactured from high-strength stainless steel, offering enhanced corrosion resistance and durability. They are designed to meet or exceed OEM specifications for fit and function, providing a reliable and cost-effective alternative.
Q: Why does the package include four pins?
A: A shear pin is a sacrificial part designed to break. It is highly recommended to keep several spares on your boat for quick, on-the-water repairs if you strike an object, so you aren't left stranded.
Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.
Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.
