Measure your prop shaft diameter and the size of your existing rudder and trim-tab zincs and the transom zinc if you have one. Also remove the engine pencil zincs from your heat ex-changers. Then go to West or eBay and match them up. You can't go wrong with CAMP zincs. Clean the surfaces real well before you install new ones, they must make a solid electrical contact. Google "How to install zincs" . You need a heavy hammer to bed shaft zincs. Cut off the excess screw length on the rudders with a hacksaw. Capt George
