We appreciate your business! Service Manuals are often referred to a repair manual, workshop manual, technical manual, shop manual, etc. Parts Manuals are often referred to as an illustrated parts list (IPL) often with exploded views, part numbers and part descriptions. Owner’s Manuals are often referred to as an operator’s manual. Product descriptions and how to use it.
Often covering very basic maintenance. Maintenance Manuals normally cover day to day upkeep, Adjustments, lubrication, oil changes, spark plugs, winter storage, etc.
Contents. Specifications It is a, vertical, diesel engine. It is built around two (hence the '2' in 2GM20) of 75 mm in diameter and 72 mm in, adding up to 0.635 litres in displacement: each cylinder is roughly the size and volume of a 300 ml. The compression system uses a proprietary swirl-type pre. The continuous rating output at the is 11.8 kW, at 3400 (rpm).
The maximum output at the crankshaft is 13.4 kW, at 3600 rpm. The engine delivers roughly 16, for a weight of about 114 kg. The engine is equipped with a starting motor (D.C. 12V, 1 kW), and an to provide electricity and charge onboard (12, 55).
The engine is typically activated by a key and a starting motor switch. Upon turning the key and pressing the starting motor switch, the oil pressure alarm will ring for about a second until the engine starts to run. The exit of cooling water from the into the sea (typically at the of the boat) should be checked at that time. After a few minutes, the hot cooling water alarm will sound if the cooling water does not get through the engine (as when the seawater cock has remained closed -most likely case- or if something is clogging the seawater tubing). Water pump. Yanmar 2GM20.
Cooling seawater enters from the tube on the left. Professional knowledge elementary study guide. The 2GM20 series uses either a, or an cooling system (specified by the suffix letter F i.e.
Is pumped into the engine through a seawater ( type). In the engines equipped with a direct seawater cooling system, seawater is used to cool the internals of the engine directly. The engines equipped with a freshwater cooling system have an additional, where heat transfer occurs between the seawater and internal. The impeller of the seawater pump can suffer from wear and tear, especially when run dry for some period of time, in which case it has to be replaced to avoid loss in the flow of cooling seawater, a potential source of engine overheating.
A particularly difficult problem in tropical waters is jellyfish. Their tentacles can be sucked into water intakes. In extremis it is possible for the rubber exhaust hose to catch fire, the plastic silencer to melt and the head-gasket to fail. In colder waters, boats are far less likely to meet such problems. The solution is to have a large basket-type water strainer and overheat alarms (standard on most Yanmar engines) The seawater pump is rotated by a short linked to the crankshaft.

Fuel filter. Yanmar 2GM20. An inline is easily accessible from the front part of the engine.
The filter retains solid particles and separates water from diesel (as water is heavier than diesel, it will settle at the bottom of the filter), just before the diesel fuel enters the highly sensitive high-pressure. Water inside diesel fuel can lead to rusting of the internals of the engine, as well as lubrication problems.
The filter element is made of fluted paper with metal end caps. When the engine has to be bled because air has penetrated into the pipes (usually after running out of diesel), it will usually be necessary to bleed the diesel filter: the top vent is unscrewed so as to let excess air escape, while diesel fuel is pumped into the fuel filter with the manual fuel lift pump (just behind the yellow ).
The vent can be screwed shut when diesel fuel starts to gush out of it. A primary fuel filter is usually installed upstream of the engine, so as to filter out the larger particles, and filter a larger quantity of water that might be present in the fuel.
Every time a filter is disassembled or changed, it will be necessary to bleed it so as to remove excess air, again by opening the top vent so as to let diesel chase all the air (diesel fills up the filter either through gravity -usually the case for the primary filter- or with the help of the fuel lift pump -usually the case for the engine fuel filter-) and diesel starts to gush out. The vent should then be screwed shut.

New models The 2GM20 and 3GM30 (three-cylinder) series have now been superseded in the Yanmar catalog by new lightweight and modernized engines, the 2YM15, 3YM20 and 3YM30. These new engines also feature simplified maintenance of the seawater pump and other services points, as they are now located on the front part of the engine. These new engines also meet new introduced in the EU and the US in 2006.
