*NOTE: Services vary by engine type and manufacturer. Service intervals were developed based upon “typical” use that includes operating at varied speeds, sufficient time for the engine warm up and cool down, medium to light loads and average cruising speed near 3000 ~ 4000 rpm range. As with any engine, if the customer's normal operating conditions are different, more frequent service should be considered, especially engine oil and gear oil. Examples might include: extended Wide Open Throttle use or long periods of idling or trolling, carrying heavy loads and frequent starting and stopping or shifting. Changing fuel formulations could require more frequent fuel filter changes and fuel system maintenance.
