How to Apply Bottom Paint to an Aluminum Outdrive

You can apply outdrive paint by either spraying with an aerosol can, or brushing it on. The best performing outdrive paint is Sea Hawk Mission Bay. Below are detailed application guidelines for spraying with the Mission Bay Aerosol Spray. The same dry times and surface preparation apply if you choose to brush Mission Bay on the outdrive.

APPLICATION: Shake can vigorously for at least 1 minute after mixing ball begins to rattle. Shake can often during use. Hold can 10-12 inches from surface and spray in short even passes to control film thickness and avoid runs. When finished spraying, invert can and spray until nozzle is clear. Allow coated unit to air dry overnight before immersion.
