Where are you located? Is there a Yanmar dealer near you?

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.


The closest I could find was something about the YSE.
