2. Watch the oil pressure gauge.
•
Oil pressure will rise as RPM increases, and fall as RPM decreases. In addition, cold oil will generally
show higher oil pressure for any specific RPM than hot oil. Both of these conditions reflect normal engine
operation.
•
If the oil indicator fluctuates when the boat is turning, climbing on plane, etc., the oil pickup screen may not
be covered with oil. Check the oil dipstick. If required add oil, but do not overfill. If the oil level is correct
and the condition persists, ask your Volvo Penta dealer to check for possible gauge or oil pump malfunc-
tion.
3. Watch the engine temperature indicator to be sure there is proper water circulation.
IMPORTANT
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, accelerate 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 accelerating to approximately ¾ throttle for two to three
minutes, 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.
IMPORTANT
For this initial two hour break-in, do not run the engine at any constant RPM for prolonged periods of time.
Next eight hours
1. During the next eight hours, continue to operate at approximately 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, momentarily increase engine speed.
3. Occasionally reduce engine speed to idle to provide cooling 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.
