I'm not sure I'd risk it on a brass/bronze prop.

It was finally used on my engine carb, as two Emersons in a ultra sonic tank hadn't work.

Why? Nothing that is in brick cleaner will have the slightest effect on a bronze (or brass) prop except dissolve any deposits just as it cleans muck off bricks. Commonly used to clean props of that type in exactly the same way as the example given.

To save disconnecting the propshaft would this be ok to trickle into the cutlass bearing to remove calcium deposits or would there be a problem with the rubber liner?

Some of the HCl storages at work are rubber lined, it shouldn't be a problem.

Brick cleaner that is dilute Hydrochloric Acid will dissolve bronze nicely given a foothold. http://nautarch.tamu.edu/CRL/conservationmanual/File12.htm

Don't know about ordinary stainless steel but HCl is fine with marine grade SS. I've used it dozens of times and watched the yard using 33% HCl, which is stronger than you can usually buy, on marine SS without a problem.
No issues with butyl rubber.

When I was researching brass and bronze seacocks I exposed them for up to 30 minutes in 20% HCl. None of them was even stained during the process.

Dilute HCl is fine to use on bronze to remove deposits. I often use it to remove deteriorated chrome or nickel plating on bronze parts with no ill effects to the bronze at all.
Overnight exposure is perfectly safe... not sure I'd leave parts immersed for months, though.

Yes it really works like magic. I have used it on my bronze prop for years with no problem.
Also cleans out the wee deposit from heads outlet lines with a great fizz.
Respectfully suggest you only do this at sea to minimise impact on wildlife

What I really fancy is something to clean my prop without a liftout. Perhaps I could infiltrate some HCl around it by pouring some into a tube that ends nearby, with a funnel of course. To hell with the wildlife - I want to go faster. Please don't take this seriously.

I always use Patio Magic to clean my stainless shafts and rudders, bronze props, and dribble it through all four cutlass bearings. When the fouling has gone then wash with fresh water. It works a treat.

you could do it electrolytically.
completely isolate your engine and transmission electrically
connect the positive terminal of your battery to the prop shaft connect the negative terminal to a chunk of copper brass or bronze ... an old pro will do. Actually an old anode would do. Lower it into the water near your prop. 'Please dont take this seriously.
