- Avoid spilling fuel.
Fuel expands when the fuel is warmed up. The fuel may overflow from the fuel tank. Inspect fuel lines for leaks. The fuel lines should be repaired if there is evidence of failure.
- Be aware of the properties of the different fuels. Use only the recommended fuels.
- Avoid unnecessary idling.
Shut off the engine rather than idle for long periods of time.
- Observe the service indicator frequently. Keep the air cleaner elements clean.
- Ensure that the turbochargers are operating correctly so that the proper air/fuel ratio is maintained. Clean exhaust indicates proper functioning.
- Maintain a good electrical system.
One worn battery cell will overwork the alternator. This will consume excess power and excess fuel.
- Ensure that the belts are properly adjusted. The belt should be in good condition.
- Ensure that all of the connections of the hoses are tight. The connections should not leak.
- When possible, utilize the heat of the jacket water system and the energy from the heat of the exhaust system.
- Keep keel coolers, heat exchangers, and water pumps clean. Keep the components in good repair.
- Ensure that all of the accessory pumps are repaired. The pumps should operate efficiently.
- Do not exceed the maximum oil level.
- Never operate without water temperature regulators.
Water temperature regulators regulate the temperature of the coolant. Water temperature regulators help to provide efficient operating temperatures. Cold engines consume excessive fuel. Water temperature regulators also help prevent engine overheating.
The recommended cruising speed of the engine is 200 to 300 rpm below the rated speed of the engine.
Operating at the recommended cruising speed will help to provide the maximum engine service life and the most economical operation.
