1. Check Fitment: Before drilling, position the guard on your motor’s lower unit to confirm it is the correct size. Do not drill holes if you are uncertain, as drilled guards cannot be returned.
2. Mark Holes: Use a marker to indicate the drilling locations on the cavitation plate and skeg.
3. Drill Holes: Using the provided drill bit, carefully drill the marked holes.
4. Mount Guard: Secure the propeller guard using the included short and long bolt sets as indicated for the upper and lower sections.

Performance Considerations: The guard may have a minimal impact on overall boat performance. To ensure optimal results, the propeller diameter should not exceed 12.5 inches. This guard is not warranted for speeds exceeding 25 MPH.

Troubleshooting & FAQ

Q: How do I know if this guard will fit my specific engine model?
A: This guard is designed for outboard motors from 40 to 65 HP with a "Class C" gearcase. It is not compatible with Big Foot or High Thrust models, which require a 14" guard. Please measure your propeller to ensure it does not exceed 12.5" in diameter and check clearances on your motor before drilling.

Q: Will this propeller guard affect my boat's speed or performance?
A: You may experience a minimal impact on performance. The guard is not recommended or warranted for speeds over 25 MPH. Performance can vary depending on your specific boat and engine configuration.

Q: What are the main benefits of installing this guard?
A: The primary benefit is safety. It helps prevent accidental injuries from propeller contact, protects marine life, and shields your propeller from damage caused by floating debris or underwater objects.
