Cold Weather Or Extended Storage; Power Package Lay-Up - Mercury 565 Manual

COLD WEATHER OR EXTENDED STORAGE

Power Package Lay‑up
IMPORTANT: This service should be performed by an authorized Mercury
MerCruiser dealer.
Without sufficient cooling water, the engine, the water pump, and other
components will overheat and suffer damage. Provide a sufficient supply of
water to the water inlets during operation.
IMPORTANT: Before starting the engine, attach a water source to the seawater
pickup pump.
1. Run engine sufficiently to bring it up to normal operating temperature.
Shut off the engine and change the oil and oil filter.
2. Flush the cooling system.
Fuel vapors trapped in the engine compartment may be an irritant, cause
difficulty breathing, or may ignite resulting in a fire or explosion. Always
ventilate the engine compartment before servicing the power package.
3. Close the fuel shut off valve if equipped.
4. Prepare fuel system for extended storage by mixing the following in a 23
liter (6 U.S. gal) remote outboard fuel tank:
• 19 liter (5 U.S. gal) regular unleaded 87 octane (R+M)/2 (92 RON)
gasoline.
• 1.89 liter (64 fl oz) Premium Plus 2‑cycle TC‑W3 outboard oil.
• 150 ml (5 fl oz) Fuel System Treatment and Stabilizer or 30 ml (1 fl oz)
Fuel System Treatment and Stabilizer Concentrate.
5. Disconnect and plug the boat's fuel line from the water separating fuel
filter inlet.
6. Connect the remote outboard fuel tank to the inlet of the water separating
fuel filter.
IMPORTANT: If the boat is out of the water, follow instructions for running the
engine on a flush device as found in the service manual.
7. Start and run the engine at 1300 RPM for five minutes.
8. After the specified running time is complete, slowly return the throttle to
idle RPM and shut off the engine.
IMPORTANT: Operating a Mercury Marine engine with gasoline containing
alcohol creates unique problems as a result of long storage periods common
to a boat. Cars normally consume alcohol‑blend fuels before they absorb
enough moisture to cause problems; however, boats often sit idle long enough
for phase separation to occur. In addition, alcohol can wash protective oil films
from internal components causing corrosion.
