CAUTION
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.
IMPORTANT: The engine must not be operating at any point during the draining procedure.

CAUTION
Disconnecting the blue drain hoses can cause serious burns due to hot water. Check all hose connections before operating
the engine and never disconnect the hoses until the engine has had suffient time to cool.

engine's cooling system or the boat. Keep the seacock or water inlet hose plugged until ready to start the engine. Attach a
tag to the ignition switch or steering wheel to inform others of the water inlet connection.
IMPORTANT: Do not start or operate the engine at any point in this procedure.
