•
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
General Information
Your authorized Mercury MerCruiser dealer can explain how to properly flush your power package.
The boat can be 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.
IMPORTANT: Engines that require dual water pickups require a through‑the‑hull or through‑the‑transom pickup in addition to the
sterndrive water inlets.
IMPORTANT: Engines with the sterndrive water inlet blocked off at the gimbal housing and using a through‑the‑hull or
through‑the‑transom pickup need a supply of cooling water available to both the sterndrive and to the engine during operation.
