• 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.
Flushing the Power Package
Your boat could come equipped with a combination of any of three different types of water
pickups: through the hull, through the transom, and through the sterndrive. The flushing
procedures for these systems are separated into two categories: sterndrive water pickups
and alternative water pickups. Consult your authorized Mercury MerCruiser dealer for
further explanation.
IMPORTANT: Bravo models equipped with closed cooling require dual water pickups and
must be equipped with a through‑hull or through‑transom pickup in addition to the
sterndrive water inlets.
IMPORTANT: Alpha engines with the sterndrive water inlet blocked off at the gimbal
housing, and using a through‑hull water inlet, need a supply of cooling water available to
both the sterndrive and to the engine during operation
