2005 Sea Ray 390 MY Air conditioning pump replacement

[Ed Bacon]

Current pump has a Baldor Reliance (no longer exists) 0.33hp 230v/60hz motor and the wet head is 4+" bronze centrifugal with 1" id input (center of wet head) and 1" id output (right shoulder of wet head as you look at the wet head). Think it's 1000gph to support 4 A/Cs. Would like a drop in 0.33hp pump with bronze head replacement. Would rather not replace with polypropylene head.
Replacement suggestions?

Is it the motor or the pump that failed?.... you might consider repairing the motor if it failed

There is a new sponsor on here might be worth a call

Look at Flagship Marine, great prices. They will have what you need

Motor running OK. Bronze centrifugal impeller pumping. Thru hulls - different flows: Cockpit - 75%, Aft stateroom - 25%, Salon - 0%, Forward stateroom - 10%. My understanding is that the flow rate of the centrifugal pump will vary if the discharge lines are constricted. I've snaked, hosed and vacuumed the three starboard thru hulls. I'm suspecting the 4-part manifold after the pump may be partially clogged with mud even though the sea strainer should capture the mud. Coda can sit on the mud at very low tides. Going to dismantle and clean manifold. If that doesn't work then I'll clean out the unit coils. If that doesn't work, then new pump.

I have both a "Sea Flush"

and a garden hose adapter for the sea strainer cap. I use Sea Flush to blow out the system with air and the adapter for a fresh water flush. I have also used phosphoric acid (Home Depot paint stripper or Barnacle Buster) to do a flush (Frank Webster did a post on this).
