Getting Started
00000 was CD912 or CE555 with different rpms in lists
Initial Break-In Procedure
It is especially important that the following procedure be used on new diesel engines. This
break-in procedure allows the proper seating of the pistons and rings, which greatly reduces
the likelihood of problems.
IMPORTANT: It is recommended that the boat not be accelerated hard until this
procedure has been completed.
IMPORTANT: Never operate the starter motor longer than 15 seconds at a time, to
avoid overheating the starter motor. If engine does not start, wait 1 minute to allow
the starter motor to cool; then, repeat starting procedure.
1. Refer to appropriate Starting, Shifting and Stopping section and start the engine.
Operate the engine at a fast idle until it has reached normal operating temperature.
2. Operate the engine in gear for 3 minutes at each of the following rpms: 1200 rpm, 2400
rpm and 3000 rpm.
3. Operate the engine in gear for 3 minutes at each of the following rpms: 1500 rpm, 2800
rpm and 3400 rpm.
4. Operate the engine in gear for 3 minutes at each of the following rpms: 1800 rpm, 3000
rpm and Maximum Rated Full Throttle rpm.

20-Hour Break-In Period
IMPORTANT: The first 20 hours of operation is the engine break-in period. Correct
break-in is essential to obtain minimum oil consumption and maximum engine
performance. During this break-in period, the following rules must be observed:
• Do not operate below 1500 rpm for extended periods of time for the first 10 hours.
Shift into gear as soon as possible after starting and advance the throttle above 1500
rpm if conditions permit safe operation.
• Do not operate at one speed consistently for extended periods.
• Do not exceed 3/4 throttle during the first 10 hours. During the next 10 hours,
occasional operation at full throttle is permissible (5 minutes at a time maximum).
• Avoid full throttle acceleration from IDLE speed.
• Do not operate at full throttle until the engine reaches normal operating temperature.
• Frequently check engine oil level. Add oil as needed. It is normal for oil consumption
to be high during the break-in period.
• AT END OF 20-HOUR break-in period, remove break-in oil and replace oil filter. Fill
the engine with the correct grade and viscosity oil.
