New problem today. (Sigh)
Friday I did the oil and filter change and put in the new impeller and ran it for 20 minutes. All was well. Today I ran it in gear after checking the level in the transmission. (Oddly enough I did have to add about 1/4" of pink ATF. Cannot feel any seepage under the trans or at the bell housing... I guess that I shall just have to check it often.)
Immediately after starting up the little raw water pump started a slow dribble of water right behind the front part of the casting. Rats.
The front plate with its new paper gasket is dry, FWIW.
After 20 years and 1880 hours I suppose it has a limit to its life, but we have plans to go on vacation in June (Note to self: man proposes, God disposes...)
When I had the pump shaft out to install the new impeller I did notice that the shaft was scored - and per the diagram there is a sleeve inside the pump housing. The oil seal in the back must be fine as ever; no seeping of oil.
Some years ago I had a mechanic friend lap the front plate to get the grooves out so it would seal and pump better.
**Sidebar: I have been cursing that front circlip annually, since 1995, BTW. Sheesh, that little piece of spring steel is hard to reinsert...
Without a shop or press, is the normal procedure just to buy another pump? Do people normally rebuild these things? Or, as is often the case, does the cost of a shaft, bushing, and labor equal the price of a whole pump?
Advice greatly appreciated.
Thanks!
Loren

Perhaps replacement is a reasonable option. I shall check pricing on a new one, just in case.
