Protect Your NK180 Motor in Shallow, Hazard-Filled Water

Rocky creeks, stump-filled backwaters, vegetation, and rough launch areas put an exposed lower unit close to hazards. The Newport NK180 HD Rock Guard adds purpose-built protection around the propeller and motor pylon while maintaining an open front for clean water flow through the prop.

Purpose-Built Protection for Newport NK180 Motors

• ✅ Purpose-built for compatible Newport NK180 motors instead of relying on a universal prop-guard design
• ✅ Three raked deflection fins help shield the propeller from rocks, stumps, roots, and submerged debris
• ✅ Integrated fins redirect weeds, roots, and vegetation to help reduce material wrapping around the prop shaft
• ✅ Wrap-around nose protection helps shield the motor pylon against direct impacts
• ✅ Nylon 6/6 composite construction is UV- and saltwater-resistant for marine use
• ✅ Partial-wrap, open-front design maintains propeller water flow with no measurable reduction in thrust or speed specified by Newport
• ✅ Direct skeg-replacement installation requires no drilling or permanent motor modification

Real-World Performance

When a kayak is working through rocky creeks, shallow flats, vegetation, or stump-filled water, the Rock Guard puts its deflection fins and nose protection between common underwater hazards and the lower unit. The integrated skeg replaces the original skeg, while the open-front configuration keeps the propeller exposed to the water flow it needs for propulsion.

Rig Your NK180 for Water with More Underwater Hazards

Add purpose-built lower-unit protection when rocks, roots, weeds, and submerged debris are part of the water you fish.
