Draining the Seawater System

Water can enter the bilge when the drain system is open, damaging the engine or causing
the boat to sink. Remove the boat from the water or close the seacock, disconnect and
plug the seawater inlet hose, and ensure the bilge pump is operational before draining.
Do not operate the engine with the drain system open.
IMPORTANT: Only drain the seawater section of the closed cooling system.
IMPORTANT: The boat must be as level as possible to ensure complete draining of the
cooling system.
Your power package is equipped with a drain system. Refer to Drain System
Identification to determine which instructions apply to your power package.
IMPORTANT: The engine must not be operating at any point during the draining procedure.
