The first MAN D2676 powered workboat is nearly ready for launch and once completed it will be put straight into operation salmon fishing in Alaska.

It was only last year that MAN Engines introduced its latest generation of in-line six-cylinder engine for workboats, the D2676.

Now it has been fitted to the LT32 Gilnetter salmon fishing boat, built by Mavrik Marine.

Mavrik Marine has already fitted a large number of its PB32 series boats with the engine’s predecessor, the D2876, which offers the same output.

But the new LT32 boat design has been modified in order to be able to operate in the even more shallow waters of the Bristol Bay area in Alaska.

The weight advantage of the MAN D2676 is a real benefit in this respect, with a dry weight of 1,200 kg, the engine is 105 kg lighter than its predecessor.

MAN’s D2676 LE443 is designed for light duty commercial operation and generates an output of 537 kW (730 HP) at 2,300 rpm with a cylinder capacity of 12.4 l. Maximum torque is 2,445 Nm at speeds of 1,300 to 2,100 rpm.

It offers low fuel consumption and low vibration levels thanks to its common rail injection system with 1,800 bar. This ensures high mean pressures and optimised fuel consumption.

The engine also complies with the current strict Tier 3 emissions legislation of the US Environmental Protection Agency (EPA).

The new MAN D2676 marine diesel engines will replace the D2866 and D2876 predecessor models. D2676 models are available for use in applications such as passenger ferries, pilot boats, fishing boats, rescue boats and more, with a variety of different power options.

The LT32 Gilnetter will be launched in late autumn.
