Re: AC raw water pump impeller replacement and source?
My only comment, if it matters, is if my a/c goes out because of the pump and I have guests on board or coming sooner than I can get a pump is that I am going to the Homo Depot and buying a swimming pool pump. Im not going to have them sit in this FL heat waiting on Oberdorfer to build me a pump thats going to take 4-6 weeks to get. I spent $400 on an obordorfer brass impeller bait well pump that was the exact one that came with the boat. While the pump looked impeccable the 32V motor they had attached to it was questionable. Didn't look like anything water resistant. Sure enough 9 months later, after the 6 month warranty expired, it crapped out. I bought a "cheap" 32volt Jabsco pump and its been running great for 3 years now. The electric motors Hatteras put on our boats don't look sealed in any way to me. Salt destroys the head motors as well as bait pumps. I haven't seen any stamps on them like UL or ABCY but maybe they are worn away. I know the starters are solid motors but cant say much for the rest of the electrical pumps. Also curious what type of 110V water pump everyone has on their boat. I have a Homo Depot well pump. Most everyone I know has a well pump. If they have caused any fires I don't know about it. I hope my engine room fire extinguishers, that passed inspection, work right cause it sounds like I am going to need them some day.

Re: AC raw water pump impeller replacement and source?
Going to get a pool pump sounds fine until you realize you don’t have the fittings to make it work. Air con is a critical system and I always carry a spare pump ready to be swapped. The best setup is when you have two pumps installed with a selector switch and a couple of valves, it s not hard or expensive to rig. If one fails you re back in business and within minutes.
And yes I have a shallow well pump (flojet) plus a DC backup.Pascal
