14" Propeller Safety Guard – Fits Most 70-120 HP Outboard Motors (Red)

14" Propeller Safety Guard – Fits Most 70-120 HP Outboard Motors (Red)

This 14-inch propeller safety guard is designed to fit most outboard motors in the 70 to 120 HP range with standard gearcases. It offers protection for both swimmers and marine life from propeller-related injuries while also shielding the propeller blades from underwater impacts with rocks or debris. This guard is compatible with propellers up to 13.5 inches in diameter and is intended for motors where the height from the center of the propeller shaft to the cavitation plate is between 6.5 and 7.5 inches. This product is not suitable for Big Foot, High Thrust, or Command Thrust models, which require a larger guard.

This is a standard safety accessory designed for broad compatibility and does not have a direct OEM equivalent part number. It is manufactured from a high-strength, marine-grade polypropylene plastic, offering impact resistance comparable to stainless steel at a significantly lighter weight.

• Installation Method: Bolts directly to the outboard's cavitation plate and skeg.
• Material: High-strength marine-grade polypropylene plastic in a high-visibility safety red color.
• Included Hardware: Comes as a complete kit with all necessary mounting bolts and a drill bit for installation.

Installation Guide

1. Safety First: Before starting, disconnect the engine's battery and ensure the engine is tilted up securely.
2. Position the Guard: Place the two halves of the propeller guard around the gearcase, ensuring it is centered and does not interfere with the propeller's rotation.
3. Mark Drill Holes: With the guard held in position, use a marker to mark the drilling locations on the cavitation plate and the skeg.
4. Drill the Holes: Carefully drill the marked holes using the provided 1/3" drill bit. Ensure the holes are straight and clean.
5. Mount the Guard: Attach the guard using the included hardware. Use the shorter bolts for the top (cavitation plate) and the longer bolts for the bottom (skeg).
6. Tighten Securely: Securely tighten all bolts. Do not overtighten to avoid cracking the plastic. Check that the guard is rigid and firmly in place.
7. Final Inspection: Manually rotate the propeller to confirm it has ample clearance and does not touch the guard at any point.

Troubleshooting & FAQ

Q: How do I confirm this guard will fit my engine?
A: To ensure compatibility, verify three key things: 1) Your motor is between 70-120 HP. 2) It has a standard gearcase, not a Big Foot, High Thrust, or Command Thrust model. 3) The distance from the center of the propeller shaft to the bottom of the cavitation plate is between 6.5 and 7.5 inches. The guard accommodates propellers up to 13.5" in diameter.

Q: Is there a maximum speed when using this propeller guard?
A: Yes, this guard is rated for a maximum speed of 25 mph. Use above this speed is not recommended and is not covered by warranty, as it can create undesirable handling characteristics and may cause the guard to fail.

Q: Why won't this fit my Big Foot / High Thrust / E-TEC model?
A: Models like Mercury's Big Foot/Command Thrust, Yamaha's High Thrust, and some Evinrude E-TECs use a larger-than-standard gearcase. These larger gearcases require a bigger (typically 16-inch) propeller guard to ensure proper clearance and fitment.

Q: Will a plastic guard be strong enough for impacts?
A: Yes. This guard is made from a specialized high-strength polypropylene. This material is designed for marine environments and offers impact resistance nearly equivalent to stainless steel, but with the advantages of being lighter and naturally corrosion-proof.

Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
