Stopping the engine immediately after it has been working under load can result in overheating and accelerated wear of engine components. Excessive temperatures in the turbocharger centerhousing will cause oil coking problems. Allow the engine to gradually cool before stopping the engine |
There may be several ways to shut off your engine. Make sure that the shutoff procedures are understood. Use the following general guidelines for stopping the engine:
- Reduce engine rpm to low idle.
- Shift into the NEUTRAL position.
- Follow one of the following steps, as recommended.
- If the engine has been operated at low loads, run the engine at low idle for 30 seconds before you stop the engine.
- If the engine has been operated at high load, increase engine rpm to no more than 1/2 rated rpm for three to five minutes.
This reduces coolant temperatures and oil temperatures. A reduction in these temperatures stabilizes internal engine coolant and oil temperatures. Then reduce the engine rpm to low idle before stopping.
- Check the marine transmission oil level while the engine is idling. Maintain the oil level between the "ADD" and "FULL" marks on the "CHECK WITH ENGINE RUNNING" side of the dipstick.
- The engine may be stopped by using one of the following engine mounted controls.

All engines are equipped with a fuel shutoff solenoid. Fuel shutoff solenoid (1) is located on the top front of the engine. The button for manual fuel shutoff (2) (if equipped) is located on the fuel shutoff solenoid. Press the button for the manual fuel shutoff. This will stop the fuel delivery to the engine. The engine will coast to a stop.
Note: Take great care to secure any external components that are used to support the engine operation.
