High Quality Content by WIKIPEDIA articles The Yanmar 2GM20 is an inboard marine diesel engine manufactured by the Japanese company Yanmar Co. Ltd.. It is used in a wide range of sailboats and motorboats. It is a four-stroke, vertical, water cooled diesel engine. It is built around two cylinders (hence the "2" in 2GM20) of 75mm in length and 72mm in stroke, adding up to 0.635 liters in displacement: each cylinder is roughly the size and volume of a 300ml soft-drink can. The compression system uses a proprietary swirl-type pre-combustion chamber. The continuous rating output at the crankshaft is 11.8 kW, and 3400 revolutions per minute (rpm). The maximum output at crankshaft is 13.4 kW, and 3600 rpm. The engine delivers roughly 20 horsepowers (hence the "20" in 2GM20), for a weight of about 114 kg. The engine is equipped with a starting motor (D.C. 12V, 1 kW), and an alternator to provide electricity and charge onboard batteries (12V, 55A).
