GENERALEngine Break-In procedureAll STEYR MOTORS Marine engines have been run for a short period as a final test at the factory. You must followthe Engine Break-In instructions during the first 20 running hours to ensure maximum performance and longestengine life.NOTE:Non-observance of break-in instructions may cause severe engine failure.First Ten HoursMaximum Engine Speed: 75 % of rated speedMaximum Throttle Position: 75 %For the first five to ten minutes of operation, run the engine at low speed (below 1,500 RPM). For the remaining firstten hours of operation, accelerate to bring boat onto plane quickly. After reaching planing reduce throttle to remainat minimum planing. For displacement or semi displacement boats the throttle position of 75 % must not be transcended.Occasionally reduce throttle to idle speed for cooling down.ATTENTION:qWarning indication engine over load during break – in via ECU (Engine Control Unit) TheECU monitors, during the first two hours of engine operation, the load on the engine. Ifthe engine is overloaded (during the first 2 hours of running) the “Check Engine Light” willautomatically illuminate. If the warning light illuminates (CEL light – ON), the throttle positionmust be reduced until this signals are extinguish.Final Ten Hours of Break-inMaximum Short Term Speed: 100 % of rated speedMaximum Short Term Throttle Position: 100 %During the final ten hours of break-in, the engine may run at full speed for five to ten minutes. The remaining hoursshould be operated up to 75 % throttle position. For displacement or semi displacement boats the throttle position of75 % must not be transcended Occasionally reduce the engine speed to cool is down.NOTE:During the break-in period, the engine must not be operated at high 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” markson dipstick. When refilling motor oil, refer to information “Engine Lubrication – Motor Oil” (page 41).B. Check oil pressure control lamp. If the lamp lights up as soon as the boat changes its position (while turning,straightening up 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 is still illuminated with correctoil level, have the engine checked by your STEYR MOTORS Marine dealer as to malfunction of signal or oilpump.NOTE:During normal operation of engine, oil pressure will rise as RPM increases and fall as RPMdecreases. In general, oil pressure will be higher with cold engine oil and specific RPM thanwith hot motor oil.C. Check engine temperature indication. Normal operation between 80° – 95°. In case of audible alarm, checkcoolant level in expansion tank (only with cold engine).D. Deviations from normal operating conditions will be indicated by warning lights and audible alarm.
