Thanks Neil!
I think I've read a few accounts of the metal (be it aluminum or cast)
deteriorating and causing the failure of the pump seal. I'll definitely have a
look at that!

Following up on Rick's comment, I found on my Whale Gusher pump that the
flappers were not working because the internal threads for the screws that hold
them in place had corroded in the tapped holes in the pump body. The metal was
some cast alloy and it wasn't just stripped threads, there was no material left
to tap oversized threads; in other words, it was junk. Maybe Devcon would have
worked, but I replaced it with a plastic body version, works fine.

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.

Subject: Stus-List Manual bilge
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’?
