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
