2. Watch the oil pressure gauge.
•
Oil pressure will rise as RPM increases, and fall
as RPM decreases. In addition, cold oil will gen-
erally 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 non-synthetic oil, but do
not overfill. If the oil level is correct and the con-
dition 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 coolant circulation.
NOTICE! 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, run
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 atti-
tude.
During this period, vary the engine speed fre-
quently by accelerating to approximately ¾ throttle
for two to three minutes, then back to minimum
cruising speed.
3. After the engine has reached operating tempera-
ture, momentarily reduce engine speed, then
increase engine speed, to assist break-in of rings
and bearings. Maintain plane to avoid excessive
engine load.
NOTICE! For this initial two hour break-in, do not run
the engine at any constant RPM for pro-
longed 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.
