Battery Storage; Power Package Recommissioning - MerCruiser Axius 350 MAG User Manual

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.

Power Package Recommissioning

1. Ensure that all cooling system hoses are connected properly and hose clamps are tight.
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.
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.
6. Carefully inspect the engine for fuel, oil, fluid, water and exhaust leaks.
7. Inspect the steering system, shift and throttle control for proper operation.
