My dealer says Grady doesn't sell replacements for my particular engine flush adapter anymore, and they referred me to freshwatersystems.com. Freshwatersystems.com told me the part is out of stock and they no longer plan to stock it. Their part number is "HFCD261257GHT Valved Female Thread Coupling Insert 3/4 FGHT". This is for a 2024 Grady White Freedom 275. Any ideas where I might buy one? Any comments on how hard or easy it would be to replace the female receptacles mounted on the inside of the transom so I can install a complete replacement?
 
Check out US Plastic

Also, you may find what you need in the outdoor garden dept at your local HD or Lowe’s
Coastbuster, Thanks for the source. Do you know if the US Plastic adapter is identical and keeps the water pressure into motors reasonably low?
 
No, I searched, “Valved Female Thread Coupling Insert 3/4 FGHT" since you checked freshwater systems part # and they’re out of stock.
 
Davis, that part is a "valved", not a pressure reducing valve. Valved means "one way".

There's no reason to limit garden hose pressure.

That product is made by Colder Products, not Fresh Water - they are just a retailer. Use the Colder ID # and you will be able to find it for sale at many places.

Keep in mind that you're only looking for a garden hose fitting, ideally valved. Although there are other ways to easily accoplish the "intent" of the valve. As noted above, it's very reasonable to think you can get the parts you need at HD... or really, anywhere. Remember, it's just a garden hose fitting.

fresh water boater here, so i have never needed to flush...

why all the flush adapter stuff? the engines have a garden hose attachment. whats needed beyond a garden hose? i dont see how it gets much easier than hooking up a garden hose
 
^^^^
My boat had a bulkhead style garden hose quick disconnect in the motor well, easily accessible from the cockpit. My boat was on a lift, so getting to the side of the motor with a hose required going on the swim platform to flush it vs a quick disconnect in the motor well..

Ekea, the engines are very close to together on my Freedom 275 and it is hard to reach the flush adapter on one of them, and it takes a few minutes to connect/disconnect each...it takes 2 seconds using the ports on the transom. That's all.
 
The legacy plumbing for plumbing is a real pain to use especially when, as mentioned, you have two motors close to each other. One of my previous boats had Mercs and the flush quickconnect flush fitting was on the back side middle of the engine. That was so much easier to work with.

While it can still be done, it's a lot harder to use the muffs if the boat is in the water. Secondly, using either the built-in hose fitting on the engine (or the remote adapter that is hull mounted) doesn't require running the engine.

Different strokes for different folks - all good in the end!
