Our most popular port-side saltwater adapter plate. This side-mounted adapter plate kit attaches to the jack plate and makes it easier to configure and install your Power-Pole Shallow Water Anchors—depending on your boat’s transom shape. Designed for port mounting, the adapter plate provides a 2-inch setback and 3-inch rise, with an added support brace for increased rigidity when using larger anchors. Made from aircraft-grade aluminum and finished with four layers of marine-grade powder coating—including a gloss black or gloss white topcoat—this adapter plate is built to resist corrosion and deliver long-lasting durability and performance.
