Troubleshooting & FAQ

Q: How do I confirm this guard fits my 9.9-20HP motor?
A: This 9" guard is designed for most 9.9HP to 20HP outboard motors that use a propeller up to 8.5 inches in diameter. It is not compatible with "Big Foot" or "High Thrust" models, as those require a larger 11" guard. Always measure your propeller diameter to ensure compatibility before purchasing.

Q: How is the propeller guard installed?
A: Installation requires drilling into your outboard's cavitation plate and skeg to create secure mounting points. The package includes all necessary stainless steel hardware and instructions to complete the installation.

Q: What is the guard made of?
A: The guard is constructed from a durable, rigid polypropylene plastic. It comes in a high-visibility Safety Yellow color to enhance underwater awareness and safety.
