Normal Engine Operation
Observe engine coolant temperature and engine
oil pressure. Temperatures and pressures will vary
between engines and with changing operating conditions,
temperatures, and loads. See GENERAL ENGINE
SPECIFICATIONS in Specifications Section near end of
manual for temperature and pressure specifications for
your engine.
If coolant temperature rises above the maximum coolant
temperature (see Specifications Section) reduce load on
engine. Unless temperature drops quickly, stop engine
and determine cause before resuming operation.
Operate the engine under a lighter load and at slower than
normal speed for first 15 minutes after start-up. DO NOT
run engine at slow idle unless necessary for maneuvering
out of dock and harbor.
Stop engine immediately if there are any signs of part
failure. Symptoms that may be early signs of engine
problems are:
•
Sudden drop in oil pressure
•
Abnormal coolant temperatures
•
High marine gear oil temperature
•
Unusual noise or vibration
•
Sudden loss of power
•
Excessive black exhaust
•
Excessive fuel consumption
•
Excessive oil consumption
•
Fluid leaks
Break-In Service
The engine is ready for normal operation. However, extra
care during the first 100 hours of operation will result in
more satisfactory long-term engine performance and life.
DO NOT exceed 100 hours of operation with break-in
oil. See GENERAL ENGINE SPECIFICATIONS in
Specifications Section near end of manual for oil pressure
and coolant temperature specifications for your engine.
1. This engine is factory-filled with John Deere Engine
Break-in Oil. Operate the engine at heavy loads with
minimal idling during the break-in period.
2. If the engine has significant operating time at
idle, constant speeds, and/or light load usage, or
makeup oil is required in the first 100 hour period,
a longer break-in period may be required. In these
situations, an additional 100 hour break-in period is
recommended using a new change of John Deere
Engine Break-In Oil and a new John Deere oil filter.
