  • Help me replace 1.5" scuppers!

    I posted this on THT and haven't gotten anywhere. I'm restoring a 1990 171 and removed the old cracked scuppers from the transom. I'm now left with 1.5" holes. Every scupper I've tried is too big or too small. I'm desperate at this point. I'm beginning to think my only
    option is to have custom scuppers made. But that can't be the only option, right? I've tried 5-6 different kinds and none have fit. Either too big or too small. They seem to be made for either a 1-1/4 hole or a 1-7/8 hole, but not a 1-1/2 hole.
    Any help is appreciated. I can't be the first guy to replace 1-1/2 scuppers on a 171.

    I know TH marine makes many different sizes? But cant say for sure they make 1-1/2" Worst case scenario can bore out to have 1-7/8"?, even more self bailing can't be a bad thing

      Lots of 1-7/8 options. They don't have a 1-1/2" option unfortunately. Unfortunately I don't think I can bore it out bigger than it is. The side of the scupper inside the boat is recessed I to the deck, and I don't think there's enough room to make the hole bigger. See the pic if that doesn't make sense.

        Looks like you could enlarge, just don’t go lower.

          I don't follow what you are looking for.
          Are you looking for the part that covers the hole or are you looking to sleeve the hole through the transom?

            Last time I replaced scupper tubes, I epoxied thin wall PVC pipe in their place...

              I replaced the brass scuppers on our 25 several years ago. I bought a Moeller flanging tool. I removed the old scupper, coated the hole with thickened epoxy then installed a new brass scupper with 5200 with the flanging tool. Maybe this will help.

                The sleeve that runs through the transom.
                originally I was thinking i could use a thru-hull for them but can't find one that will for the current hole.

                  Someone in THT mentioned getting this-
                  https://tdibrass.com/products/1-5-di...nt=36853513288


                  and flaring each side of it once I cut it to size. I don't see ANY moeller flanging tool for 1.5" pipe though. It's always 1", 1-1/4", or 1-7/8".

                    I used thickened epoxy to bed a piece of PVC pipe for my drain plug hole.

                      So just cut a piece of pvc (or stainless) to the exact thickness of the transom, slather it in 4200, and shove it in?

                        I replaced my brass sleeves with PVC also. I didn’t use 4200 I used thickened epoxy.

                          Would marine Tex work? Or would I need something more specialized?

                          EDIT- Thickened epoxy is the name of the epoxy. Got it. I'm not familair with all the different epoxies and goo's out there. But if I ever finish this project I'm sure I will be. Looks like this thickened epoxy only comes in a full size caulk tube. I think I need about 1/4 of that at most.

                            Check out this website https://www.westsystem.com/wp-conten...anual-2016.pdf
                            There is a lot of information about their epoxies.
