I think you might find that the bilge pump you have is a Whale Gusher. At least the pump in my 75 vintage 25 mk1 was a Whale.
My problem was not the diaphragm but the flapper valves in the inlet and outlet of the pump. They no longer sealed properly after 25 or 30 years in place. A relatively inexpensive rebuild kit and a few hours labor fixed the problem. On my 25, the pump is mounted on the bottom side of the cockpit sole. The hardest part of the repair was crawling down there to remove the pump and then reinstalling it later. Which reminds me I need to add a pump rebuild to the list of projects on my 38.

Would one try to find a new diaphragm to replace it or install a better system in the lazarette, such as a whale or something similar? Do they even make replacement diaphragms for a 1978 26’?
