Replace brass through hull fittings in cockpit of 1622

I have a 1622 that is taking on some water in the bilge. I think the brass through hull fittings that lead to the cockpit might be leaking. How difficult are they to replace? Are the parts/tools required available and reasonably priced? Thanks!

    Same thing was happening in my 1720, pretty easy to do. You'll need a 1 inch flanging tool, some 1 inch brass tubing, and some 5200. I emailed action craft and he kind of went over it for me, let me see if I can pull up the email.

    The drain tubes are 1” outside diameter and 4 “ long when purchased. The only cautions/suggestions that I have when replacing drain tubes:

    1. Be careful when removing old tubes. If old tube is removed improperly it could enlarge the holes in the hull and liner.
    2. When preparing to install the drain tube, install the tube from the inside of boat and mark length of drain tube utilizing the contour of the hull (this will provide the best seal when crimping the new tube in place).
    3. Apply 5200 liberally to both the inside flange and outside of the drain tube when installing (excess can be cleaned up easily utilizing acetone).
    4. When crimping/flanging new tube into place utilize caution not to over crimp/flange tube. When crimped/flanged the tube should not distort hull or liner.

    I paid about 35 for the tool and I think about $6 for each tube. I'd loan you the tool if you are up near st. Augustine.
    And I got the old brass tube off with a dremel with a small wheel.

    Jakeh, thanks so much for the info. How did you verify that the brass tubes were leaking? My plan (based on Internet research) is to plug both holes from the cockpit and have someone spray the drain/hull with a hose while I am looking at the bilge for water.

    You used a Dremel to cut off the flange. Did you use pvc or something similar to push the old tube out? Thank so much for your offer of loaning the tool. I'm in Sarasota so will need to buy one. Is this the appropriate tool? 1" od

    Yep that's the tool. While the boat is in the water I could see small amounts of water coming in, i tried to smear some silicone around it but that didn't work. But your method should work fine. Once I cut the tube I just used some pliers to push it through.

    I though I had the same problem. I just 5200'd around the flange on both sides. I use mineral spirits to clean up the 5200 works great! I'm sure acetone works fine too, dave would know! The guys at AC are awesome and very helpful.
