Troubleshooting & FAQ
Will this hardware kit fit my engine?
This kit is a universal replacement for BRP Evinrude outboards requiring OEM part 175268. While it fits a broad range of models, it is most commonly specified for 20-35HP engines. To ensure compatibility, please verify your part number against our Part Number Matrix.
When should I replace my propeller hardware?
It is best practice to replace your propeller nut and cotter pin every time you replace your propeller. You should also install a new kit immediately if you notice any signs of corrosion, thread damage, or wear.
What are signs of a failing propeller nut or cotter pin?
Telltale signs include excessive propeller vibration, rattling or clunking sounds from the gearcase area, or visible corrosion and wear on the nut or pin. A loose propeller can cause poor performance and potential damage to the driveshaft.
Can I reuse my old cotter pin?
No. Cotter pins are single-use safety items. Reusing a pin dramatically increases the risk of failure, which could lead to the loss of your propeller and costly damage. Always use the new cotter pin supplied in the kit.
