D 4 Engine Break-In procedure
The following procedure must be used on new and rebuilt STEYR Diesel Engines. You must follow the Engine
Break-In instructions during the first 20 running hours to ensure maximum performance and longest engine life.
NOTE: NONOBSERVANCE OF BREAK-IN INSTRUCTIONS MAY CAUSE SEVERE ENGINE
FAILURE.
First Two Hours
For the first five to ten minutes of operation, run engine at a fast idle (below 1500 RPM). For the remaining first
two hours of operation, accelerate to bring boat onto plane quickly and bring throttle back to maintain a planing
attitude.
During this period, vary the engine speed frequently by accelerating to approximately three-fourth throttle for two
to three minutes, then back to minimum planing speed.
When the engine has reached operating temperature, reduce engine speed, then increase engine speed again,
to assist the break-in of rings and bearings. Maintain planing attitude to avoid excessive engine load.
NOTE: DO NOT RUN ENGINE AT A CONSTANT RPM FOR LONGER PERIODS
DURING THIS INITIAL TWO HOURS OF BREAK-IN.
ATTENTION: Warning indication engine over load during break - in via ECU
The ECU controls during the first two hours of engine operation the load on the engine and
alarms the drive by the "Check Engine Light", if much power is demanded from the new
engine.
In case the operator get alert, when running the engine during break in phase, by this
"Break - In" warning indication (CEL light - ON), the throttle position must be reduced
until this signals are extinguish.
Next Eight Hours
For the next eight hours, continue to run engine at approximately three-fourth throttle or less (minimum planing
speed).
Occasionally reduce throttle to idle speed for cooling down. During this eight hours of running it is permissible to
run at full throttle for periods of less than two minutes.
NOTE: DURING BREAK-IN, DO NOT RUN ENGINE AT A CONSTANT RPM
FOR LONGER PERIODS.
