After 5 years of trying to find filters for my motors I came across these filters have now used for the past year and will replace at next service
and cut open etc for a look inside
griffin G11-10 cost AU$59 each as replacements
for the Yanmar
4230B/4231 Spin on water
seperator type filters cost AU$100 each
Still not as cheap
as you would think they should be but the save me $80 on my two motors per service
In USA may be a lot cheaper?
Of cause it is up to each individual to decide on what they use.
