RETAINER 2255248 - Caterpillar

The 3600 Series Fast Vessel Engines are intended to provide main propulsion for fast vessels. The engines are rated from 750 rpm to 1000 rpm.Engine Service Life
Engine efficiency and maximum utilization of engine performance depend on the adherence to proper operation and maintenance recommendations. This includes use of the recommended lubricants, fuels,and coolant/antifreezes.For the engine maintenance that is required, see the Operation and Maintenance Manual, "Maintenance Interval Schedule" in the Maintenance Section.Engine Specifications
