Protect Your Newport Motor in Rocks, Weeds, and Shallow Water
Rocky shorelines, submerged roots, vegetation, and rough launch areas can put an exposed lower unit in harm's way. The Newport NK300/NT300 HD Rock Guard adds purpose-built protection around the propeller and motor pylon while preserving the water flow these motors were designed around.

Real-World Performance
When fishing rocky creeks, shallow flats, stump-filled backwaters, or vegetation, the guard places its three fins and wrap-around nose between common underwater hazards and the motor's propeller and pylon. The integrated skeg replaces the original skeg, while the open-front design maintains water flow around the lower unit instead of fully enclosing the prop.
Add Protection Where Your Newport Motor Needs It
Equip an NK300 HD or NT300 for water where rocks, roots, weeds, and submerged debris make lower-unit protection worth adding to the setup.
