Relationship YANMAR and LARSNES

The relationship between LARSNES and YANMAR is one of mutual trust and respect. Back in 1997, when YANMAR had just entered the European marine market, Larsnes was the first shipyard in Norway to trust YANMAR as the preferred engine supplier for their vessels. This has led to a strong, stable partnership ever since. Both companies share the same core values to deliver optimal solutions at all times: innovation, high-quality awareness and customer loyalty.

Jarle Gunnarstein, CEO of Larsnes Mek. Verksted AS

"Our ships have had YANMAR engines for over 20 years; also on board of MS Gunnar K. Why? Because right from the start customers have always been very satisfied, especially with the fuel economy and low emissions of the engines. For us as a builder the simple installation and accessible maintenance are most important."

Rolf Kristoffersen Chairman and captain of Kristoffersen Fiskebåt AS

"We needed a heavier engine with more torque to control all operations on the ship simultaneously, including the shaft generator and propeller, without loss of energy. The YANMAR 6EY22AW delivers all the power we need, and trouble-free. I had already heard positive stories about YANMAR from fellow companies, and I can only agree with that."
