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.

• Inspect the sacrificial trim tab or anode plate if equipped, at regular intervals and replace
it before it is half gone. If a stainless steel propeller is installed, additional anodes or a
MerCathode System will be required.
• Inspect the propeller shaft for fishing line, which can cause corrosion on a stainless
steel shaft.
• Remove the propeller at least every 60 days and lubricate the propeller shaft.
• Do not use lubricants containing graphite on or near the aluminum in saltwater.
• Do not paint trim tabs or the mounting surface.
