Our marine engines for auxiliary applications give you low cost of ownership, excellent fuel economy and competitive prices both for engine and parts. Auxiliary engines generate a vessel's on-board electricity, so they need to be quick to start and feature low noise and low emissions. For heavy duty requirements, such as powering a large fishing vessel's electrically driven net haul system, you really need the extra power that a dedicated auxiliary engine will give to you – rather than generating electricity from the propulsion engine.

Gear-driven water pumps ensure maximum cooling efficiency. Inserted valve seats, oil spray cooled pistons and compact plate oil cooler give enhanced engine life.

Low cost of ownership

Competitive engine and parts pricing, 500 hour service intervals and low fuel consumption ensure our engines bring significant owner savings.

Low noise and low emissions

Our auxiliary marine engines give exceptionally low noise and are designed to meet a variety of emission standards.

Reliable power

High compression ratios ensure rapid starting in all conditions. Engines suitable for operation in ambient temperatures up to 50°C and seawaters up to 38°C. Fuelled starting aids for temperatures down to -15°C.
