For all marine transmission lubrication and maintenance activities, refer to your marine transmission or vessel OEM literature.Use fuel consumption, service hours, or calendar time, whichever occurs first, to determine maintenance intervals. Experience has shown that maintenance intervals are most accurately scheduled on the basis of fuel consumed rather than service hours.Daily
Walk-Around Inspection - Inspect engine for leaks and loose connections Engine Crankcase - Check oil level Cooling System - Check coolant level Air Cleaner - Check service indicator/Service air cleaner when needed Air Starter (If Equipped) - Check lubricator oil level Clutch (If Equipped) - Check/Adjust/Lubricate Marine Transmission - Check oil levelEvery 2550 L (675 gal) of Fuel or 50 Hours
