Final Ten Hours of Break-in
During the final ten hours of break-in, the engine may run at full speed for five to ten minutes. After warming up
the engine to operating temperature, momentarily reduce the engine speed and then increase it again. For cooling
down the engine, occasionally reduce the engine speed.
NOTE:
DURING THE BREAK-IN PERIOD, THE ENGINE MUST NOT BE OPERATED AT
CONSTANT RPM FOR LONGER PERIODS.
During break-in period, be particularly observant of the following:
A. Check motor oil level daily. Always maintain oil level in the desired range between the "MIN" and "MAX" marks
on dipstick.
When refilling motor oil, refer to information "Motor Oil" (B 2).
B. Check oil pressure control lamp. If the lamp lights up as soon as the boat changes its position (while turning,
raising the boat or planing), check the oil level in the engine housing by means of dipstick. If necessary, add
oil (DO NOT OVERFILL). In case that the oil pressure control lamp still illuminated with correct oil level, have
the engine checked by your STEYR Marine dealer as to malfunction of signal or oil pump.
NOTE:
During normal operation of engine, oil pressure will rise as RPM increases and
fall as RPM decreases. In general, oil pressure will be higher with cold motor
oil and specific RPM than with hot motor oil.
C. Check engine temperature indication. Normal operation between 80° - 95°. In case of audible alarm, check
coolant level in expansion tank (only at cold engine).
D. Deviations from normal operating conditions will be indicated by warning lights and audible alarm. As to exact
meanings see 06.07.02 & 06.07.05.
ATTENTION: In case of nonobservance of break-in instructions, warranty will expire.
Engine to be filled with recommended oil quality only. See chapter "Engine Lubrication"
