Outdrives & Props
Bronze and aluminium are the materials that need protecting in these areas as they are prone to the same level of fouling and corrosion as all underwater metal areas. As these areas directly effect the efficiency and safety of the propulsion of the boat it is most important that they are correctly maintained.
Due to the excessive movement and water turbulence in these areas, the endurance of any coating is tested, particularly on the propeller. Care should be taken never to overcoat the anodes as this will adversely effect their performance.
Thoroughly clean areas to be coated using Yacht Cleaner and freshwater. Abrade with 80-120 grade abrasive paper. Wash thoroughly with fresh water and allow to dry before applying relevant specification.
Use Mille Antifouling due to its metal free properties.
Due to the excessive wear and tear in this area, repainting generally involves a complete strip back and full specification.
