The authorized repair folks have been hard to find but I finally got a
good response and things are on the way. I found the Service Bulliten
#632 on the Kohler website.

BTW. I dug enough chunks and bits from an old impeller out of my heat
exchanger to make a new impeller out of and she now runs great. It was
really easy to extract the exchanger and I din't have to replace any
seals.

Oh! I hate to ask where the zink should go? I haven't seen anything
mentioned about it anywhere! Is it a pencil like my crusaders?

Now you got me thinkin...

I may be mistaken. It may have just been a drain hole with no facility for
a zinc but I have a hard time with the fact that there'd be no zinc on the
seawater side of a heat exchanger.

Yes, if I'm right it's the pencil type. May be located elsewhere on your
model.
