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!

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.

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 :) Chris Sent from Yahoo Mail for iPhone On Wednesday, October 17, 2018, 9:10 PM, Rick Brass via CnC-List <cnc-list@cnc-list.com> wrote: 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’?
