3. Watch the engine temperature indicator to be sure
there is proper water circulation.
NOTE! Failure to follow the break-in procedure may void
the engine warranty.
First two hours
1. For the
first five to ten minutes
of operation, operate
the engine at a fast idle (above 1500 RPM).
2. During the
remaining first two hours
of operation, ac-
celerate to bring the boat onto plane quickly; bring the
throttle back to maintain a planing attitude.
During this period, vary the engine speed frequently by ac-
celerating to approximately ¾ throttle for two to three min-
utes, then back to minimum cruising speed.
3. After the engine has reached operating temperature,
momentarily reduce engine speed, then increase engine
speed, to assist break-in of rings and bearings. Maintain
plane to avoid excessive engine load.
Next eight hours
1. During the next eight hours, continue to operate at ap-
proximately ¾ throttle or less (minimum cruising speed).
Occasionally reduce throttle to idle speed for a cooling
period.
2. During this eight hours of operation you may operate at
full throttle for periods of less than two minutes.
Final ten hours
1. During the final ten hours of break-in, you may operate
at full throttle for five to ten minutes at a time.
2. After warming the engine to operating temperature, mo-
mentarily increase engine speed.
3. Occasionally reduce engine speed to idle to provide cool-
ing periods.
At the end of the 20 hour break-in period, drain the engine
oil and replace the oil filter. Fill the crankcase with Volvo
Penta’s DuraPlus™ premium engine oil labeled for Service
CE/SG. For the 4.3OSi, 5.0OSi, 5.7OSi and 5.7OSXi, use
Volvo Penta’s DuraPlus™ synthetic engine oil.
First service inspection (Dealer
20-hour check)
To ensure your continued boating enjoyment, we recommend
that you return your Volvo Penta product to your Volvo Penta
dealer for a 20-hour check. This 20-hour check will prevent
a minor problem from getting worse, and helps ensure a
trouble-free boating season. When following the Volvo Penta
guidelines, your dealer will service these items:
Start the engine and check that
•
No leakage of fuel, oil, water, or exhaust gases occurs.
•
Engine oil pressure and temperature are normal.
•
All cables and controls operate correctly.
•
All gauges, instruments, and alarms operate correctly.
•
Steering system operates correctly.
•
Engine ignition timing and idle RPM are within specifi-
cations.
•
Power trim system operates correctly.
Stop the engine and
•
Change engine oil and oil filter.
•
Change fuel/water separator filter.
•
Clean seawater strainer (if equipped).
•
Check fluid levels and fluid condition in sterndrive or in-
board transmission, power steering pump, and trim
pump.
•
Check propeller(s) and propeller(s) fasteners.
•
Check condition of battery and battery cable connec-
tions.
•
Check drive belt(s) tension and condition.
•
Lubricate all grease fittings and linkages following ser-
vice recommendations.
•
Check tightness of all water, fuel, and exhaust clamps,
fittings, and drain plugs.
Restart the engine and recheck that
•
No leakage of fuel, oil, water, or exhaust gases occurs.
•
Engine oil pressure and temperature are normal.
This is a perfect time to discuss with your Volvo Penta dealer
any questions about your engine that may have arisen dur-
ing the first 20 hours of operation and establish a routine
preventive maintenance schedule.
