I'[[ chime in a little here. Here in Chicago we have short Lake Michigan season - about 5 months. On my early model A4 I upgraded from a little "Sherwood" pump to the Ober about 25 years ago. With the old style Dole tstat the beast runs a steady 140 F raw water. I pull the shaft out/impellar out every season for winter layup carefully using small needle nose pliers and lubricate it. I did slightly bevel the shaft end to minimize seal damage on extraction /install. every other outing I give the grease cup a half turn After examining the impeller I usually change every 2 -3 seasons no matter [snap ring is important] and change the moyer gasket almost every year. Cooling/pump has been problem free so far with this routine.
