need help with Yanmar YSB12 diesel
The large diameter hole you are looking at, is indeed the air intake. There
should be a semi-circular air induction tube casting attached there. Boats don't normally have an air filter. I know of no substitute for the fuel filter, although you could substitute a completely different assembly I suppose. The filter elements are still readily availabe. Your engine was manufactured in 1976 or 1977, but the YSE and YSM versions, which were manufactured two years previous to, and after the YSB respectively, are the same engine in most respects. -- Steve Thomas "lupi" wrote in message ... Ahoy, I just bought a small boat with a Yanmar YSB12 diesel in it. It was owned by hooligans and it seems part of the motor is missing. There is maybe some kind of hose missing in the front of the engine. It's directly above the water pump and is an inlet about 2 inches around. I can see some type of valve inside. This is the air intake? Is there a picture on line somewhere so I can see what's missing? Would a generic air filter and housing coupled to a tube work well enough? Also, is there an inexpensive auto store filter that replaces CAV 296, a paper filter that goes in the water trap? Also, what kind of off-the-shelf oil can I use? There doesn't seem to be a lot of info out there concerning these engines other than that they vibrate violently at low rpm. I am in the usa. Thanks for your time. |

Check out these sites for Yanmar related questions- they have message
boards specific for Yanmar engines and you can even order parts: http://www.yanmarhelp.com/msgboard.mv http://www.torresen.com/ Yes- that is the air-intake- do not use any paper-type filter or auto filter. Get the manual for your engine and it explains everything you need to know. I have a YSM12- the manual really helps. Good luck! "Steve" wrote in message ...
