c. Install the appropriate flushing attachment over the water inlet holes in the gear housing.
4. Connect the hose between the flushing attachment and the water source.
5. With the sterndrive in normal operating position, open the water source completely.
6. Place the remote control in the neutral idle speed position and start the engine.
NOTICE
Operating the engine out of the water at high speeds creates suction, which can collapse the water supply hose and overheat
the engine. Do not operate the engine above 1400 RPM out of the water and without sufficient cooling water supply.
7. Depress the throttle only button and slowly advance the throttle until the engine reaches 1300 RPM (± 100 RPM).
8. Observe the water temperature gauge to ensure that the engine is operating in the normal range.
9. Operate engine with sterndrive in neutral for about 10 minutes or until discharge water is clear.
10. Slowly return the throttle to the idle speed position.
11. Stop the engine.
12. Shut off the water and remove flushing attachment.
13. This step is only required if the boat is to be stored in the water. After the flush procedure is completed, remove the
seawater inlet hose from the thermostat housing and plug the hose to prevent water from siphoning into the boat. This
prevents seawater from contaminating the engine flush.
14. Tag the ignition switch with an appropriate tag requiring the seawater inlet hose to be reconnected prior to operating
engine.
Flushing the Power Package (Bravo)
General Information
Your authorized Mercury MerCruiser dealer can explain how to properly flush your power package.
Flushing the 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.
