Consultancy, Design, Development and Testing of Custom-Built Engines

The Special Products Division of E. P. Barrus Ltd is a dedicated team set-up to design and develop custom-built engines and accessories to meet the specific operational requirements of its professional customers. The team has the experience and knowledge to solve the stringent requirements and applications of specialist organisations including professional rescue services, the military and other government and commercial organisations.

Custom-Engine Building and Test Facilities

Barrus has made a substantial investment to create one of the world’s largest and most modern custom-engine building facilities at the company’s headquarters in Bicester, Oxfordshire. This enables Barrus to build engines in single units to production runs in excess of 100. Barrus’ test facilities enable delivery of fully tested run-in and first serviced engines. Barrus facilities include

Five dynamometers capable of testing diesel engines up to 1600hp, with Europe’s only non-captive sterndrive dyno, a variable down-angle dyno and the world’s only Fabio Buzzi Trimax drive compatible dyno.
Two overhead mono-rail production lines capable of taking outboard engines up to 350hp and inboard engines up to 500hp.
An outboard test cell which can accommodate up to eight 350hp engines with transoms from 15” to 30”.
A machine shop and welding centre for prototype and low volume manufacture.
A dedicated engine overhaul area
A spray booth with warm air ventilation for superior paint finish

Mariner Outboard Engines

Mariner outboards have an awesome reputation for reliability and durability with the latest engines delivering an unsurpassed level of smooth power, fuel efficiency and emission levels. Barrus supply Mariner 2-stroke engines from 4 to 250hp and Mariner Optimax engines from 75 to 115hp for numerous commercial applications.

Post Immersion Restart Engines

Barrus leads the field in the development of Post Immersion Restart Engines for use in rescue and military operations. The unique, patented FAST PIRS^TMsystem enables an engine to be restarted after complete submersion within just 40 seconds. This entails evacuating all the water from the cylinder head, transfer ports and fuel system.

Multi-Fuel Outboard Engines

Another example of Barrus innovation is the multi-fuel 50hp outboard engine. This was designed and developed for the UK MoD and is capable of running on four different NATO fuels.

Rescue and Disaster Relief

Air Lift Able Pump

Utilised by H.M. Coastguard search and rescue helicopters, the 2” trash pump with a lightweight air portable frame can be used for salvage, fire fighting and general pumping.

Salt Water Pump

A Yanmar powered Barrus supplied salt water pump that is ideal for applications on salt water and mild base chemical.

SeaSearch Inflatables

SeaSearch inflatables from 3.9 to 4.2m have heavy-duty aluminium floors and can be rowed or powered by Mariner outboard engines up to 30hp.

MoD Emergency Relief Generator

The MoD specification Emergency Relief Generator is powered by a low noise, air-cooled, single cylinder Yanmar engine. The rugged frame with a durable electrophoretic coating makes it easy to move around and will withstand the rigours of continuous operation.
