Section 6 - Storage
6. Pump air into the system until both green indicators extend and water drains from both
sides of the engine. The port side will begin draining before the starboard side.
7. Verify that water is draining from each opening. If not, use the Manual Drain System
instructions.
8. Allow the system to drain for a minimum of five minutes. Pump air as necessary to keep
the green indicators extended.
9. For DTS engines, pull the lanyard stop switch (if equipped), or disable the ignition circuit
by pulling the fuse marked "CD".
10. Crank the engine over slightly with the starter motor to purge any water trapped in the
seawater pump. Do not allow engine to start.
11. Remove the air pump from the air manifold and return it to the mounting bracket.
12. Mercury MerCruiser recommends leaving the drain system open while transporting the
boat or while performing other maintenance. This helps ensure that all water is drained.
