Flushing the Power Package
General Information
Your authorized Mercury MerCruiser dealer can explain how to properly flush your 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.
