Troubleshooting & FAQ
How do I know if this guard will fit my specific motor?
This guard is designed for most 25-35 HP outboard motors. However, it excludes certain models like Mercury's "Big Foot" and Yamaha's "High Thrust" series. Always compare the product images and specifications to your engine's lower unit before purchasing to ensure compatibility.
Is drilling required for installation?
Yes, installation requires drilling into the engine's cavitation plate (the flat plate above the propeller). A 1/3" drill bit is included in the package for this purpose.
What is the maximum recommended speed with this guard installed?
It is not recommended to operate your boat at speeds exceeding 25-30 mph with this guard installed, as it can affect handling and performance at higher speeds.
Will this propeller guard affect my boat's performance?
A propeller guard introduces additional drag, which may result in a slight reduction in top speed and acceleration. The exact impact can vary based on your boat, engine, and propeller setup.
What tools are required for installation?
You will need a wrench or socket set to tighten the bolts, a power drill for creating the mounting holes, and a propeller wrench to remove and reinstall your propeller.
Why is the guard a bright orange color?
The "Safety Orange" color provides high visibility in the water, making the propeller's location clear to swimmers, divers, and wildlife, which helps prevent accidental contact.
