replacement diaphram on bilge pump needed

Hi, I need to replace the diaphram on my manual bilge pump in my 1980 Union 36. I am unable to find a manufacturer's name on the pump, but the diameter of the rubber (?) diaphram is 10 inches. Anyone out there have any suggestions? Thanks

Probably a Whale pump. Many Gusher 10s were installed as bilge pumps. See the link to see if yours matches any of them.

While the pump might be a stock item from someone like Whale, there is also the chance that, like the knock-off winches that overseas builders used to make, they may have done the same with a pump.
Diaphram pump designs are kinda generic anyhow...

As long as the rest of the parts are in good order, perhaps you could source some reinforced rubber fabric and cut out a new diaphram, maybe.
