It took awhile to get around to pulling the lower unit and opening the pump assembly. I believe the seller was telling the truth when he said it hadn’t been in the water since the early 70’s. The inner surface of the pump was pretty badly corroded. I scraped the corrosion off, Scotch-brited it and finished it off with 400 grit WD sandpaper. I regret not buying the entire assembly vs just the impeller but will do so the next time.
I was going to start a new thread to ask a generic question but will do so here instead. What are the disadvantages, if any, of putting a film of water proof grease on the inside of the pump housing before reassembly? I can give plenty of benefits especially in light of how badly pock marked the inside was but would like to know why its not a good idea.
I haven’t tightened anything up yet so it’d be relatively easy to open it back up and wipe off the grease if I should.
THANKS again!
