That very well could be it Rick!! I haven’t pulled it apart or really gotten 
into it yet and it may need to wait for spring as the days are shorter and the 
snow is on its way. 
I wasn’t sure if there was a check valve in the system or not and the previous 
owner was unsure. She has a brand new electric bilge pump but not sure that has 
a check valve either. Something I was going to install next season 
Thanks for the tip. I’ll see what I find :)

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.

The diaphragm on the manual bilge pump in the cockpit seems to be compromised. 
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’?
