The 3508 marine diesel engine from Caterpillar has several key systems that contribute to its reliability and efficiency. To begin with, the air inlet system includes a corrosion-resistant coated circuit after cooler core and regular duty air cleaners with service indicators and dual turbochargers.

The control system features a dual Caterpillar A-111 electric engine control with a rigid wiring harness and an electronic unit injection fuel system. The cooling system is highly dependable thanks to several components, including an auxiliary fresh water pump, a non-self-priming pump for sea water, and a centrifugal jacket water pump that is gear-driven. 

The engine has a lube system with various features such as oil filters, an oil cooler, and an oil filler. The mounting system includes engine-length ledge-type mounting rails, and the power take-offs feature an accessory drive on the lower RH and LH with a two-sided front housing. To ensure the engine is well-protected, the module has an A-111 electronic monitoring system with engine deration strategies that can be programmed. The engine also features protection against over-speeds and safety shut off protection for water temperature and oil pressure, as well as an emergency stop push button.
