Maintenance 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 condition persists, ask your Volvo Penta dealer to check for possible gauge or oil pump malfunc- tion. 21194 3.
Watch the engine temperature indicator to be sure there is proper coolant circulation. 21195 CAUTION! Failure to follow the break-in pro- cedure may void the engine warranty. 7743722 - Downloaded from www.volvopenta.com 13/05/2008 20:17:06 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 ѕ throt- tle 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. CAUTION! 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 ѕ throttle or less (minimum cruising speed). Occasionally reduce throttle to idle speed for a cooling period. 22812-1 2. During this eight hours of operation you may operate at full throttle for periods of less than two minutes. 62 VPA 7743722 English 10-2004
