Installation Guide

This guard attaches to the outboard motor's cavitation plate and skeg. It is designed for motors where the measurement from the prop shaft to the underside of the cavitation plate is 6.5" to 7.5". Installation requires drilling.

1. Position the guard on the underside of the cavitation plate, ensuring there is equal distance between the guard and the propeller blades.
2. Position the guard as far forward on the cavitation plate as possible for optimal protection and performance.
3. If your motor has a trim tab located under the cavitation plate, it must be removed before installing the guard.
4. Drill 6 holes through the cavitation plate and the guard on each side.
5. Insert the provided bolts, washers, and nuts, and only loosely tighten them at this stage.
6. Drill one final hole through the lower skeg, insert the corresponding bolt, washer, and nut, and tighten it securely.
7. Once the skeg bolt is secure, proceed to tighten all the cavitation plate bolts evenly.

Troubleshooting & FAQ

Q: How do I know if this guard will fit my specific motor model?

A: This guard is a universal fit for most 40-65 HP outboards. The key is to ensure your motor does not have a "Big Foot" or "High Thrust" lower unit, your propeller is no larger than 10.5" in diameter, and the distance from the prop shaft to the cavitation plate is between 6.5" and 7.5". Always measure before ordering.

Q: What is the maximum speed I can go with this guard installed?

A: The guard is designed for speeds up to 25 mph. It is not warranted for use at higher speeds, as this can put excessive stress on the guard and the motor's lower unit.

Q: Does this guard affect my boat's performance?

A: Like any propeller guard, it can introduce slight changes in handling, acceleration, or top speed due to increased drag. However, it is designed to minimize these effects while providing crucial safety protection.
