ENGINE WARM UP
CAUTION
Improper or no warm-up of engine can seriously impair the Iife of your diesel engine.
1 After starting, check to ensure all instrumentation is functioning properly. Run engine at 1,000 to 1,200 rpm
until engine temperature is within normal operating range. It is very important that any engine be warmed up
before applying full load. The warm-up period provides time for the lubricating oil to establish a film between
moving parts.
NOTE: Engine warm-up time during cold weather can be reduced by operating vessel at reduced engine speed.
Commence normal vessel operation when systems reach operating temperatures.
2 After the engine has reached operating temperature:
A Oil pressure should be within range listed in the engine specifications chart. Stop the engine if oil pressure
is not within this range.
B Check the fuel system for leakage from the injection pump, fuel pipes, fuel filter and fuel lines.
C Check for oil leakage. Check the engine and sterndrive unit for oil leakage. Especially check the oil filter, oil
lines, oil line connectors, and oil pan.
D Check for coolant leaks. Check coolant hoses and connection pipes of heat exchanger, fluid coolers, inter-
cooler, water pump and drain fittings.
3 Locate and correct any problems, or see your Authorized Mercury MerCruiser Dealer if you are unable to
determine the problem.
