Yanmar Engines

Yanmar engines go further and they work harder, year after year.

Yanmar diesel engines are renowned for their rugged reliability. With their economical operation and reduced downtime, it's little wonder that successful water sports professionals rely on Yanmar for enduring power. Little wonder that major charter fleet operators turn to Yanmar. Little wonder that award-winning boat designers specify Yanmar from the start.

The Yanmar Marine range includes the single cylinder 1GM10 (9hp), the YM series (14hp, 21hp & 29hp) and the recently-revised JH series (39hp, 54hp, 75hp & 110hp). All Yanmar engines up to 75hp are available with a saildrive.

The new BY series of engines is the latest generation of Yanmar diesels with four- and six-cylinder models (150hp, 180hp, 220hp & 260hp) whilst the 6LPA is available as a 315hp six-cylinder. All these engines are available as sterndrives with a choice of the Bravo 1, 2 or 3 drives. Please contact us for details of the LY series (370-480hp), LY3 series (380-480hp) and SY series (720-900hp).

GM Series

Yanmar GM Series

The Yanmar 1GM10 is well-known as a reliable and dependent workhorse for smaller yachts and launches and it is a best seller across the world.

YM Series

Yanmar YM Series

The YM series comprises the two-cylinder engines 14hp 2YM15 and the three-cylinder 21hp 3YM20 and 29hp 3YM30. These big displacement Yanmar diesels give more power, easy starting and outstanding torque at low engine speeds. The new design means quieter, smoother and cleaner running than precious generations, yet with traditional Yanmar values of quality and dependability.

The new Yanmar 3YM30 AE is introduced in 2015 and features the same power output at its predecessor at a lower rpm for improved quietness, as well as a larger capacity engine block for improved torque and reliability.

With the added benefit of simplified maintenance due to the new location of the sea-water pump and all other service points being together near the engine front these units no doubt are already on track to be recognized as the best-in-class auxiliary power for sailboats and tough, reliable primary power for small motor craft.
