  • Side Hull Deck Drains - Pros & Cons

    I'm getting to the point in my rebuild where I need to start thinking about my deck drains and am thinking about putting them in the side if the hull instead of the transom. Has anyone done this and how do you like it. I found these and think it might be a good option.

    I thought long and hard about it on my 25 and wanted to do something like Grady White does on their boats. I've seen many other brands that go out the side and it's not a big deal if you can make sure the fitting on the hull doesn't protrude too much and catch water, plus you might need a clam shell to make sure water doesn't get forced into the hull. I've seen a cat that had the round white scupper flaps turned so the flap hinge faces forward which seemed to work but at the water line I would think they would catch water and cause spray. Grady uses a stainless thru hull with an internal rubber flap built in and I wouldn't want to have anything protruding through that is not metal.

      I agree with the above. I have issues on my 17 if it gets sloppy. Water can get forced in the bildge drain.

        I appreciate the responses. I'm gonna go ahead and rethink my transom thru hulls and go that route.

          Ive thought about the same thing. Ive actualky considered keeping aft and adding side drains. I agree with sailor if you do it go with SS with neoprene flapper.

            When I replaced my transom on my 254 last year, I moved mine to the side. I have had no issues and it solved my problem of water coming in when I am holding over a fishing spot in reverse. Mine have no flapper and are generally above the water line.

              I haven't had any issues. I moved mine to the side because the transom thru hull was in the way of the trim tabs

                Mrdelgado, what thruhull did you use. I couldn't find any that were stainless and had a finished look on the inside. I didn't really want the hex nut showing on the inside. I didn't think about them getting in the way of the trim tabs. I'll have to take some measurements for that and go from there. The only problem I have is I have no idea where the water line is. As soon as I got the boat I started tearing it apart. So it's all a guess with the weight changes I've made. I'm also thinking about waiting till the boat is all but painted then drop it in the water to get the waterline and then make up my mind on the deck drains. Got any pics of the inside.

                  Mine look like The picture above. On our boats you can not see the back side without opening up a hatch. Mine have a nipple that is connected to a hose that connects to a nipple that I fiberglassed to drain channels on the deck. I think I purchased mine from Gemlux. I would not drill a hole in the side or any where else near the waterline without knowing the water line.

                    Yeah, figure out your water line first. As you can see in my sig pic, the drain is a good 2" above the water line.

                    I think I grabbed these off Greatlakesskipper. They're a 2" stainless drain with four 3/4" fittings in each. The deck drains, locker drains, livewell overflows and livewell drain are all plumbed to these thru hulls. sorry no pics on hand of the inside, but its the same big nut threaded on, then a 4" long extension with four threaded 3/4" holes to put barbed fittings in.
