So I was able to do some testing before and after I rebuild the jabsco 36800 pump. It's rated for 3.3 gal/minute and before I did the rebuild it pumped 2 gallons out in 35 seconds, which is about 3.4 gal/min. not too bad. after the rebuild it took 30 seconds, which is 4 gal/min. So worth it. the rubber gaskets were pretty deformed--see pics.
