Boring has Yanmar
parts. They make a ''spares kit'', there was one in my
boat
when I got it.

You should always carry at least two spare impellers. I
put one in
two years ago and it failed within ten hours - the vanes
spun freely
on the hub.

I have a new one and a good old one as spares.


Frankly I don't see why people buy the parts year by
year; why not buy 4 or 5 years worth and always know you
have a stash?

What if you sell the boat?
I buy oil filters by the case for my trucks, had 6 left over
when I switched from a Detroit to a Cat.
I still have filters for my '71 Dodge van. Anybody need
one?
