POWER UNIT - MULTIPLE ENGINE REMOVAL - AND RUN-IN INSTRUCTIONS
g. Cooling System.
Remove the heat exchanger tank cap SLOWLY after the engine has reached normal operating temperature and
check the engine coolant level. The coolant level should be near the top of the opening. If necessary, add a high boiling
point type antifreeze.
h. Marine Gear.
Check the marine gear oil pressure.
Avoid Unnecessary Engine Idling.
During long engine idling periods, the engine coolant temperature will fall below the normal operating range. The
incomplete combustion of fuel in a cold engine will cause crankcase dilution, formation of lacquer or gummy deposits on
the valves, pistons and rings and rapid accumulation of sludge in the engine.
When prolonged engine idling is necessary, maintain at least 800 rpm.
Release the load and decrease the engine speed. Allow the engine to run at half speed or lower with no-load for
four or five minutes before closing the throttle and stopping the engine.
The emergency shut-down system should never be used to stop the engine except in an emergency. Use of the
emergency shut-down can cause oil to be sucked past the oil seals into the blower housing.
b. Fuel System.
If the unit is equipped with a fuel valve, close it.
