Yanmar Key - 2QM15
David,The Yanmar 2QM15 works flawlessly. It is really the little engine that could. We purchased the boat last summer and it was running a little rough and finally stoped running. TUrned out that we had water in the fuel. After pumping the water out of the fuel tank, refilling with new deisel fuel, we bled the fuel lines for water and the engine started right up. Now before we start it up, I drain a little fuel out of the ware trap and it runs like a charm.Rick
