I've just found in my spares box a Sub Tech "SBS-2 Prop Shaft Stuffing Box with seals"...it seems to be a length of brass tube about 2" long with bronze bushes either end, and two(?)internal O ring seals. According to the brief instructions, it must be fitted in one way only, which is described on the packet.
I'm guessing it would take a 1/4" prop shaft, which I could then connect to the stub shaft by using a standard Huco type coupling.
I take it that this can be fitted into the end cap of a wtc, with the prop shaft passing through it to make a water tight seal?
Anyone ever used one of these?

Usually a 3/16" shaft.
They use lip seals, but I believe they don't use a spring like the simmering seals.
As a consequence, they're not designed to be used in an enclosure that isn't internally pressurized;the seal works to work against external (water) pressure.
Mike Shubar at Mike's Subworks still sells these. Dop him a line if you have any further queries-
