Why This Guard

• Built from marine-grade stainless steel for strength and corrosion resistance
• Covers and reinforces an already damaged skeg—often no welding required
• Integrated drain ports help purge water to reduce freeze and corrosion damage
• Sleek, low-drag profile helps protect the gearcase from future impacts

Installation Notes

• Dry-fit first and confirm your gearcase is 4-3/4" diameter
• Verify clearance to the prop and anti-ventilation plate
• Mark and drill pilot holes if required; use a quality marine sealant on fasteners
• Tighten fasteners evenly; recheck torque and clearance after the first run

Fitment tip: Measure your existing skeg and confirm engine model/year before ordering. If you’re unsure, contact us with your model and serial for a quick confirmation.
