[C320-list] strainer basket gasket

[Gene Helfman]

Raw water on Satori (#398) goes from the "Kingston Cock" valve intake
through a strainer basket and on to the engine. The strainer basket seals
with a flat-sided, 55mm diameter gasket (like an o-ring but flat, not
rounded). This part and the strainer basket are not figured in the parts
manual for the Yanmar 3gm30f. Does anyone know the part number and where
one might find it.
thanks,
gene
