Details

The Rock Guard is the first purpose-built prop and motor pylon protection solution for Newport electric outboard motors. Engineered specifically for Newport NK180 HD and NK180PRO, the Rock Guard protects your propeller by deflecting rocks, roots, ramps and debris before they reach the blades.  We also designed in a wrap-around nose protector to shield the motor pylon against blunt impact. Built in armor, made for hydrodynamic performance, preserves clean water flow so thrust and speed are unaffected.

Built from marine-grade materials rated for UV exposure, saltwater, and hard impact, the Rock Guard is ready for the water where fish actually live. Installation is fast, with included stainless hardware; no modifications required. It fits because it was built for your motor.

Frequently Asked Questions

You know how they say there’s no such thing as a dumb question? Well, they were wrong, but here are some common not-so-dumb ones

Which motors does the Rock Guard fit?

This fits both the NK180 HD and NK180PRO

Will the Rock Guard reduce my motor's speed or thrust?

No. The guard uses an open-front design that maintains full water flow through the propeller. You should see no measurable reduction in thrust or speed.

Is the Rock Guard saltwater safe?

Yes. It's built from UV-stabilized, saltwater-resistant, impact-resistant materials.

How does it install?

It mounts directly to your motor housing using the included stainless hardware and an Allen key. No modification or custom fitting required.

Does it prevent weeds from wrapping around the prop shaft?

Yes. Integrated deflection fins are designed to redirect weeds, roots, and vegetation away from the shaft before they can wrap.
