This is a rather hard to find original brass plunger type water pump for an old marine engine or other type of engine. It is in good, used condition with very little wear consistent with age. The plunger moves as it should. The body of the pump mounts with two holes 2 1/8 inches apart on center and has 1/4 npt threads in it. If you need one for any reason this one should serve the purpose. It would also make a great spare on the shelf. These original brass water pumps are almost impossible to find in. The wild or even at swap meets so don’t miss your chance one this one. The pictures tell the story. You won’t be disappointed in any way. I can be reached at 262-573-193 1 if you’d like to talk about it.
