Parts Desk Insights
This complete kit is the right choice for BRP/OMC Cobra stern drive owners who operate in saltwater or brackish water and want to replace all anodes at once during annual maintenance or haulout. Replacing all anodes together ensures uniform protection and eliminates the risk of leaving a depleted anode in place. The included hardware and installation instructions make this a convenient all-in-one solution. Aluminum is the preferred material for saltwater and brackish water use, providing better galvanic protection than zinc in marine environments.
