Engine Operation
Proper operation and maintenance are key factors in obtaining the maximum life and economy of the engine. Following the directions in this manual will lower operating costs.Check all gauges during the warm up period. Generally, more warm-up time is needed when the temperature is lower.The time needed for the engine to reach the normal mode of operation is usually less than the time taken for a walk-around-inspection of the engine. Make another inspection after starting the engine.Check the engine for fluid and air leaks. Check for any cooling system leaks or loose connections. Check for lubrication leaks, such as the front and rear crankshaft seals, crankcase, oil filter, oil gallery plugs and sensors, and valve covers. Measure the crankcase oil level on the LOW IDLE side of the dipstick. Maintain the oil level between the ADD and FULL marks.Make sure fuel lines are properly clamped and tight. Check for loose fittings or leaks.Measure the marine transmission oil level at LOW IDLE. Refer to the marine transmission OEM literature for lubrication maintenance recommendations.After the engine has warmed and inspections have been made, increase the engine speed and observe the sea water discharge. If the water flow is restricted, stop the engine. Inspect the cooling system and the water pump(s) for evidence of leaks. Perform any necessary repairs before operating the engine.
If water is not visible, or if water flow is restricted, stop the engine. The engine will overheat. Inspect the inlet screen and the sea water strainer for debris. Remove any debris if present.
Check the gauges and equipment for proper operation. Always increase engine speed before applying the load. Begin operating the engine at low load. The engine will reach normal operating temperature faster when operated at low speed and low power demand than when idled at no load. Typically, the engine should reach operating temperature in a few minutes. After normal oil pressure is reached and the temperature gauges begin to move, the engine may be operated at partial and then full load.If the load varies, or is cyclic, the governor will adjust the engine speed as required.Extended operation at low idle or reduced load may cause increased oil consumption and carbon build-up in the cylinders. This carbon build-up results in loss of power and/or poor performance. When operating at reduced load, the engine should be fully loaded to burn excess carbon from the cylinders at least every four hours. Check the gauges and equipment frequently while operating under load.Gauges readings should be observed and the data recorded frequently while the engine is operating. Comparing the data over time will help determine normal readings for each gauge, and help detect abnormal operating developments. Significant changes in the readings should be investigated.Engine and Marine Transmission Operation
Shifting the Marine Transmission
Full power is transferred from the engine, through the marine transmission, to the propeller shaft. The power may be transferred in either forward or reverse rotation. The marine transmission forward and reverse drives can be operated by mechanical, hydraulic, pneumatic,
