We recommend the following maintenance items to help keep your sterndrive
corrosion‑free:
• Maintain a complete paint covering on the sterndrive.
• Check the finish regularly. Prime and paint nicks and scratches using Mercury enamel
paint and touch up paint. Use only tin–based anti–fouling paint or its equivalent on or
near aluminum surfaces below the waterline.
• If bare metal is showing, apply 2 coats paint.
