Two new auxiliary engines – powering the marine sector.

Perkins marine has just launched its new Perkins® E44 and E70B auxiliary engines for use on inland waterways, tugs, governmental, fishing and ferry services at the Marine Equipment Trade Show in Amsterdam.



The new Perkins® E44, an electronic 4.4 litre, 4-cylinder engine and the evolved E70B offer a broad range of power ratings and factory configurable power solutions to meet vessel and operator auxiliary power needs.

Perkins engineers put your needs first

“Our customers require more, and we are here to meet their expectations,” comments Ben Lewis, sales support manager at Perkins marine engines. The electronic engines are highly engineered and durable as Perkins understands that high engine uptime is a priority. “Customers in need of auxiliary power with a high-power density without compromising fuel efficiency or additional noise, need to look no further.”

New to the auxiliary range is the E44, an electronic 4.4 litre, 4-cylinder engine. Just as you have come to expect from all Perkins engines, it offers a 500-hour interval service, low maintenance features, and high-power density. A self-priming common rail fuel system, no zinc anodes, automatic valve adjustment and self-tensioning belts. These features all add up to exception uptime.

The larger more powerful E70B is an evolution of the E70-TAG with the same prevailing features of a Perkins engine; high power density, excellent fuel economy with fewer maintenance touchpoints for exception uptime.

The E70B is an advancement based on customer feedback. Specific features have been incorporated for the OEM market and third party generator set packagers. In particular, the low-pressure fuel system and electrical systems are now engine mounted and there is no engine base – this simplifies the packaging requirements and reduces the space required for the engine.

The product development team have put the customer first with the E70B, as we understand that repower is an important part of their business. Repower has been taken into consideration and the E70B comes with an optional single circuit keel cooling system. This engine is destined for inland waterways, tugs, governmental, fishing and ferry services boats - working boats. The E70B’s new variable speed option is intended for variable speed generator set applications and running of variable speed auxiliary deck equipment.

New engine offerings

Targeting end users including generator set packagers and hybrid propulsion packers in the workboat, inland waterways, tug, and large yacht/superyacht sector, customers can choose from multiple cooling options, depending on the application, repower and ease of integration. All engines are designed and assembled in the UK using the highest quality parts, offering our customers a competitively priced engine and spare parts.

With space onboard at a premium, the engines are compact in their design and simple to install with easy plug and play features for a complete turnkey solution. They also offer easy access to service points and factory configuration is available. The open order board for the new E44 and E70B is at the end of quarter 4, 2023.

The technical bit

E44 ratings

71 bkW (95 bhp) to 108 bkW (145 bhp) at 1500 rpm

71 bkW (95 bhp) to 129 bkW (173 bhp) at 1800 rpm

E70B ratings

109 bkW (146 bhp) to 163 bkW (218 bhp) at 1500 rpm fixed speed

128 bkW (171 bhp) to 216 bkW (289 bhp) at 1800 rpm fixed speed

129 bkW (173 bhp) to 186 bkW (249 bhp) at 2400 rpm variable speed

The E70B meets IMO II, U.S. EPA T3 and EU V emissions standards on ratings below 130 bkW, whilst the E44 meets U.S. EPA T3 and EU V – falling below the minimum requirement for IMO certification. Both platforms are available with full MCS approval on request.

Launched at METS

“There was only one way to unveil the E44, a highly anticipated new engine to our marine customers and that was at the world’s largest exhibition of marine equipment – the Marine Equipment Trade Show METS) in Amsterdam!” comments Benita Liepina, sales support specialist for Perkins marine engines.

“We were delighted with the reaction from customers who were keen to see and learn more about our offering. We look forward to seeing the first of these engines delivered in Q1 of 2024 and learning more about how customers of Perkins are using them.”
