Draining Instructions - Mercury 565 Manual

COLD WEATHER OR EXTENDED STORAGE
IMPORTANT: Do not run the engine's fuel system dry of this fogging mixture
in the 23 liter (6 U.S. gal) remote outboard fuel tank.
NOTE: Refer to Fuel Requirements for additional information.
9. Close fuel shut off valve, if equipped.
10. Place drive unit in the full down position.
The universal joint bellows may develop a set when stored in a raised or up
position, causing the bellows to fail when returned to service and allowing
water to enter the boat. Store the sterndrive in the full down position.

Draining Instructions

Water trapped in the seawater section of the cooling system can cause
corrosion or freeze damage. Drain the seawater section of the cooling
system immediately after operation or before any length of storage in
freezing temperatures. If the boat is in the water, keep the seacock closed
until restarting the engine to prevent water from flowing back into the cooling
system. If the boat is not fitted with a seacock, leave the water inlet hose
disconnected and plugged.
NOTE: As a precautionary measure, attach a tag to the key switch or steering
wheel of the boat reminding the operator to open the seacock or unplug and
reconnect the water inlet hose before starting the engine.
IMPORTANT: The boat must be as level as possible to ensure complete
draining of cooling system.
1. Remove the following drain plugs:
• End of exhaust manifold balance rail (plastic wingnut plugs, port and
starboard)
• Fuel cooler (plastic wingnut plug, below engine front)
