I just picked up a pretty darn clean 85, 500 for $1000. The water pump housing has a lot of corrosion though. Does anyone have an idea if the newer models will interchange? It looks like the hose outlets are pointing in different directions. Thank you

Yep, the newer covers will fit and yes there is a hose change required.
There is a thread here that talks about it.
Do a search and see if you can find it.

I have a few pics in my $200 86 thread.
