So I'm having troubles with my 1985 Mercury 60hp. I've replaced my impeller the old one didn't really look bad but I hear they can be so I just changed it. Checked the lines all the way through and nothing is clogged. She just won't pump, I might come off as stupid but is the copper pipe running up through supposed to go into some sort of line because I can't find it anywhere. It's hard to see because the boat is outside on a trailer and I am having a hard time seeing up in there to see if there is a line or slot for it. Any info would be great thank you!!
