Installation Guide

Professional installation is recommended. The following is a general guide:

1. Safety First: Before starting, disconnect the engine's battery and remove the spark plug wires to prevent accidental starting.
2. Position the Guard: Slide the two halves of the propeller guard over the lower unit, with one half above the cavitation plate and the other below the skeg.
3. Align and Mark: Ensure the guard is centered and does not interfere with the propeller's movement. Mark the drilling locations on the cavitation plate and skeg through the mounting holes on the guard.
4. Drill Holes: Remove the guard. Using the included 8.5 mm drill bit, carefully drill the marked holes through the cavitation plate and skeg.
5. Secure the Guard: Re-position the guard halves and fasten them securely together using the provided stainless steel bolts and nuts. Tighten all hardware evenly.
6. Final Check: Manually rotate the propeller to ensure it spins freely without touching any part of the guard.

Troubleshooting & FAQ

Q: How do I confirm this guard will fit my engine?

A: This 9-inch guard is designed to fit propellers with a diameter up to 8.5 inches.
