AC raw water pump impeller replacement and source?

[Briankinley2004]

Most of the folks I know replace theirs with a swimming pool pump of equal gpm. They are about $200 bucks and made for salt water. My oferdorfer is still going but thats my plan when she goes out. Plus they are on the shelf at Homo depot so they can be had pretty quick. Several boats I have been on had them with a screen built into the pump you can put bromide tabs in. I have heard of people using irrigation pumps as well.

Well the only boat I have ever seen with swimming pool pump also had an RV air con... the March pumps are top notch and last a long time...

Bronze impeller and o-ring is about $105 from www.pumpvendor.com and would make an easy repair for me if the impeller loosens right up and doesn't need to be shimmed. That March option looks good once I have used my spare motor and pump.

The swimming pool pumps sound ok. But I wonder if they are rated for marine use viz ignition source or for a wet bilge installation. I suspect not, hence, swimming pool rating.

All this A/C talk got me to clean the strainer when in the ER this afternoon. Someone left me a little surprise in the basket:

I don't know if the PO or the A/C guy put those copper pipe pieces in there. I guess it works because the strainer was very clean after a lot of use for the last couple months.

Oh, by the way, where can I get the gasket to go in the a/c strainer in my 52C? It's a mess and now the thing leaks after cleaning it.

You make one. Not difficult.

Perko or Groco?
The synthetic or cork gaskets are readily available, usually on the rack at West Marine.
Close the cock and take the cover to the store if your not sure of the model number or size.

For the tru hardened, I always keep a sheet of various gasket material in the shop and press (tap out) my own gaskets for strainers.

marine use viz ignition source

Excuse the interruption Sensei.... but no propane and no gasoline.... who cares about sparks?

I know of at least three boats running the swimming pool pumps that have passed multiple annual inspections by the USCG. All of them are diesel and not gas.
