Erik, I replaced the scuppers in my 1987 cuddy. I used a wooden dowel ( 1 inch I think) to drive the brass original ones out. then I replaced them with plastic scuppers and 5200 to seal them. I had a hard time finding ones long enough to fit the transom thickness. It turned out that ones from T-H marine (the manufacturer) were the only ones that would work. It seems that they were 3 1/4" long. They make 2 sizes.

In my search I discovered you could use brass scuppers, but you needed a tool to swage (flare the end) after it was pushed through the hole. It seems like the tool was maybe $25 and the plastic ones that I found were substantial enough to make me comfortable enough with them. Hope that helps out.
