IMPORTANT: When filling the coolant section after it has been completely drained, the engine should be level or slightly lower
at the flywheel end.
1.
Remove the coolant reservoir cap from the coolant reservoir.
2.
Fill the reservoir to the full mark with the recommended coolant solution.
3.
Replace the pressure cap.
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.
4.
Supply cooling water to the engine.
5.
With the engine running, check the hose connections, fittings, and gaskets for leaks. Also observe the engine temperature
gauge to ensure that the engine operating temperature is normal. If the gauge indicates excessive temperature, stop the
engine immediately and determine the cause.
A sudden loss of pressure can cause hot coolant to boil and discharge violently, resulting in serious injury from burns. Allow
the engine to cool down before removing the coolant pressure cap.
6.
After the engine has cooled completely, recheck the coolant level and add coolant, if necessary.
7.
If the reservoir was completely emptied of coolant, a significant amount of air remains in the cooling system. Refill the
reservoir to the full mark, repeat the warm‑up/cool‑down cycle, and check the coolant level again.
8.
Maintain the coolant level in the reservoir at or near the full mark with the engine cold.

Checking
Discharge of oil, coolant, or other engine/drive fluids into the environment is restricted by law. Use caution not to spill oil,
coolant, or other fluids into the environment when using or servicing your boat. Be aware of the local restrictions governing
the disposal or recycling of waste, and contain and dispose of fluids as required.
NOTE: The oil level fluctuates during operation, so check with the engine cold before starting.
1.
Check the gear lube level. Keep the gear lube at the recommended level.
