5041339 EVINRUDE * THROTTLE SHAFT

This engine meets EPA Tier 3, Euro Stage III, or MOC Step 3 emission regulations. The standard oil change interval is 250 hours. Oil change intervals of 500 hours are available, provided that operating conditions, recommended multigrade oil types, SOS oil sampling, analysis program , and IR (infrared) are used to determine the acceptable oil change interval. Refer to the "Optimizing Oil Change Intervals", PEDP7035 in order to determine oil changes.If you select an interval for oil and filter change that is too long, you may damage the engine.
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact the skin.
Caterpillar oil filters are recommended for oil changes. Recommended multigrade oil types are listed in Table 1. Do not use single grade oils.

Commercial oils that are licensed by the American Petroleum Institute (API) bear this trademark. Commercial oils that do not bear this trademark are not licensed and these oils are not recommended. Oils that are not listed in Table1 are not recommended.
Abnormally harsh operating cycles or harsh environments can shorten the service life of the engine oil. Arctic temperatures, corrosive environments, or extremely dusty conditions may require a reduction in engine oil change intervals from the recommendations in Table 1. Poor maintenance of air filters or of fuel filters requires reduced oil change intervals. See your Caterpillar dealer for more information if this product will experience abnormally harsh operating cycles or harsh environments.

(1) The standard oil change interval in this engine is 250 hours, if the operating conditions and recommended oil types that are listed in this table are met. Oil change intervals may be increased to 500 hours, depending on the type of oil, quality and operating conditions. Refer to Special Publication, PEDP7035, "Optimizing Oil Change Intervals" in order to determine if the oil change interval can be extended beyond 250 hours.
(2) Normal conditions include these factors: Fuel sulfur below 0.3%, altitude below 1830 m (6000 ft) and good air filter and fuel filter maintenance. Normal conditions do not include high load factor, harsh operating cycles, or harsh environments.
(3) High load factors can shorten the service life of your engine oil. Continuous heavy load cycles and very little idle time result in increased fuel consumption and oil contamination. These factors deplete the oil additives more rapidly. If the average fuel consumption of your engine exceed 43 L (11 US gal) per hour, follow the “High Load Factor” recommendations in Table 1. To determine average fuel consumption for your engine, measure average fuel consumption for a period of 50 to 100 hours. If the application of the engine is changed, the average fuel consumption may change.
(4) For sulfur content above 0.5%, refer to, "Total Base Number (TBN) and Fuel Sulfur Levels for Direct Injection (DI) Diesel Engines" in Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations".
(5) In order to verify an oil change interval of 500 hours, refer to "Program A" below.
(6) Use "Program B" below to determine an appropriate interval.Adjustment of the Oil Change Interval
Note: Your Caterpillar dealer has additional information on these programs.Program A
Proceed to Program B.
Change to a preferred oil type in Table 1.Program B
Optimizing Oil Change IntervalsBegin with a 250 hour oil change interval. The oil change intervals are adjusted by increments. Each interval is adjusted an additional 50 hours. Periodic oil sampling and analysis is done during each interval. The analysis includes oil viscosity and infrared (IR) analysis of the oil. Repeat Program B if you change the application of the engine.If an oil sample does not pass the analysis, shorten the oil change interval, or change to a preferred multigrade oil type in the listing above.References

After the engine has been run at the normal operating temperature, stop the engine. Attach a "DO NOT OPERATE" or a similar warning tag to the ignition keyswitch before the engine is serviced. Catch the oil in a suitable container. Recycle the used oil, or dispose of the used oil properly.
Remove the oil drain plug in order to allow the oil to drain.
After the oil has drained, the oil drain plug should be cleaned and install
