TROUBLESHOOTING
Refer to the Yanmar manual for service and troubleshooting guide. Diesel engines have a
reputation for being very reliable provided they are serviced regularly and best quality diesel
engine oil, fuel filters and water impellors are used. There is an old adage for diesel engines
that give them clean fuel, the best oil and good cooling water flow that they will go forever.
Air or air bubbles in the fuel will stop the engine. They will be evident in the fuel pre-filter bowl.
The source of this air will most likely be seating of the fuel pre-filter but other fuel hose
connections need to be checked also. An engine will usually start once the air is passed through
the fuel injectors. If it does not start then a more technical process of bleeding the fuel system
is required. This is a simple process for a qualified mechanic and can be done by technically
inclined owners.
Overheating will also stop an engine. A check that good coolant water flow is coming out the
exhaust should be done every time an engine is started. Poor flow is most likely caused by
coolant water pump impellor failure or debris covering the sail drive leg water inlet. The sail
drive water inlet can be checked by snorkeling under the boat. Coolant water inlet grates are
located on each side of the sail drive leg about half way down. Coolant water impellors would
normally be replaced with every engine service. Impellors can fail prematurely that are poor
quality or take in abrasive material such as sandy silt. Spare impellors should be kept on board.
Engine controls should be regularly lubricated and adjusted if necessary to ensure smooth
operation. Engine controls that are not smooth to operate should be immediately serviced.
