Battery Storage; Power Package Recommissioning - MerCruiser Sterndrive 4.3L TKS Owner's Manual

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 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 the
engine to the lowest temperature to which it will be exposed during freezing
temperatures or extended storage

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.
Reversing the battery cables or connection order will damage the electrical system. When
installing the battery, be sure to connect the positive (+) battery cable to the positive (+)
battery terminal first, and the negative (–) battery cable to the negative (–) battery terminal
second.
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.
Overheating from insufficient cooling water will cause engine and drive system damage.
Ensure that there is sufficient water always available at water inlet holes 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.
