Foot Operated Bilge Pump

When I was about 12 years old, a fellow a couple houses from us down passed away. I was asked to come by his garage/shop and pick out anything that I found interesting. This is one of the 3 items I remember selecting even though I had no interest in boating at the time. Interestingly enough, the other two items were also boating related, but that's a story for another time.

It's a foot operated bilge pump which uses a toilet plunger cup.



 But after all these years the plunger part has hardened and split.
I was in the Dollar Store the other day and spotted a plunger for $1.

For a buck I brought it home to see if it would fit - and it does. So I was able to overhaul a 60 year old pump for a measly dollar by only opening up the top of the cup.
The cup comes with a closed neck.


All the parts of the pump



This is the bottom of the base. The holes are covered on the other side by a rubber disc fixed only in the center. This is the "intake" valve.


The top piece is a friction fit over the cup stem using a brass disc as the 'exhaust' valve.

Quite an ingenious set up that allows pumping the bilge without using your hands (like for rowing or hanging on?)
