NOTICE
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.
2. Lower the sterndrive unit to the full down/in position.
3. For additional assurance against freezing and rust, after draining, fill the cooling system with propylene glycol mixed to the
manufacturer's recommendation to protect engine to the lowest temperature to which it will be exposed during freezing
temperatures or extended storage
IMPORTANT: Mercury MerCruiser requires that propylene glycol antifreeze, mixed to the manufacturers instructions, be used
in the seawater section of the cooling system for freezing temperatures or extended storage. Make sure that the propylene
glycol antifreeze contains a rust inhibitor and is recommended for use in marine engines. Be certain to follow the propylene
glycol manufacturer's recommendations.
Battery Storage
Whenever the battery will be stored for an extended period of time, be sure the cells are full of water and the battery is fully charged
and in good operating condition. It should be clean and free of leaks. Follow the battery manufacturer's instructions for storage.
Recommissioning the Power Package
1. Ensure that all cooling system hoses are connected properly and hose clamps are tight.
!
CAUTION
Disconnecting or connecting the battery cables in the incorrect order can cause injury from electrical shock or can damage the
electrical system. Always disconnect the negative (‑) battery cable first and connect it last.
2. Install a fully charged battery. Clean the battery cable clamps and terminals and reconnect cables. Tighten each cable clamp
securely when connecting.
3. Coat the terminal connections with a battery terminal anti‑corrosion agent.
4. Perform all the checks in the before starting column of the
Operation Chart
.
NOTICE
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.
5. Start the engine and closely observe instrumentation to ensure that all systems are functioning correctly.
