Seacore Power Package Flushing Procedure; Models Using The Sterndrive Water Pickup - Mercury 350 MAG Manual

Section 5 - Maintenance

SeaCore Power Package Flushing Procedure

NOTE: Flushing is needed only for salt, brackish, mineral laden or polluted water applications. Flushing is recommended after
each outing for best results.
IMPORTANT: Flushing the SeaCore power package with the boat and sterndrive in the water is less effective. Flushing the
SeaCore power package is most effective when performed with the boat and sterndrive out of the water, such as on a boat lift or
trailer.

Models Using The Sterndrive Water Pickup

IMPORTANT: The system is designed to flush the Bravo sterndrive and the engine with one water source. Do not block or remove
the inlet water hose from the sterndrive to the engine.
NOTE: Engines with the sterndrive water inlet blocked off at the gimbal housing: Refer to Alternative Water Pickups.
Rotating propellers can cause serious injury or death. Never operate the boat out of the water with a propeller installed. Before
installing or removing a propeller, place the drive unit in neutral and engage the lanyard stop switch to prevent the engine from
starting. Place a block of wood between the propeller blade and the anti‑ventilation plate.
IMPORTANT: Do not allow the engine to pull air or seawater from alternative water pickup sources during the flushing procedure.
If equipped, ensure that all alternative water inlet hoses are plugged at both ends.
1. Remove the boat from the water.
2. Close the seacock, if equipped.
