The Thornycroft 90 and 108 engines are both 4 cylinder, 4 stroke naturally aspirated high speed diesel units, both engines having electrically operated heater plugs to aid cold starting.

The cast iron crankcase with ribbed sidewalls houses a forged steel, fully counterbalanced crankshaft carried in three or five bearings respectively.

A full pressure wet sump lubrication system is employed with a full flow detachable element type oil filter and integrated lubricating oil cooler.

The cooling system is indirect and usually employs an engine mounted heat exchanger with a belt driven raw water pump. This system is known as IFWC (internal fresh water cooled).

An optional system is EFWC (external fresh water cooled.) This system utilizes the engine fresh water pump and usually employs skin tanks attached to the hull to serve as heat exchangers.

The single belt driven alternator and fresh water pump drive include a manual belt tensioning arrangement for low maintenance completes the comprehensive engine package.
