Additional Notes
The Caterpillar 3516C Marine Engine is part of Caterpillar’s Commercial Marine Propulsion range and is available in multiple power ratings to suit different vessel and propulsion requirements. The engine configuration can vary according to the selected rating, propulsion arrangement and vessel application.
Caterpillar documentation identifies a range of standard and optional equipment for the 3516C, including different air-intake, fuel, cooling, lubrication, starting, exhaust, instrumentation and monitoring configurations. The actual equipment installed on an individual engine should therefore be verified against the applicable engine specification and serial number.
Filter and service-component requirements may vary with the engine arrangement and installed equipment. The Caterpillar 3516C Marine Engine should therefore be matched to the applicable Caterpillar documentation when identifying replacement filters, filter elements and other service components.
Technical specifications, equipment configurations and replacement-part applications should be verified against the relevant Caterpillar documentation and the installed engine before ordering or replacement.
