- Here you will find a video about how I installed through hull transom scuppers on my 1981 Catalina 22. I hope this video helps you.
The link below might not work in the future but folks can search 1-1/8” marine thru hull on the web, Amazon, etc.
These fittings are also available at most marine supply stores.

Thanks for the video. Just did mine today. The link and part number were good, but not long enough for my hull. There wasn't much threat to screw on to. I also had to do silicone both sides because the butyl tape wouldn't compress. Might redo it. Might just put it in the water and see what i think and tey again next year. We'll see...
Looks like a good upgrade.
Also, I just used a 2-inch piece of white PVC pipe - cut it flush, and silicone them in. they look fine and have worked well w/o a problems
Hey man I did the exact same project on my Catalina 22.
A trick for the butle tape for you:
Once you put the beetle tape around the threads against the cockpit hole or on the washer however you want to do it, put just a little bit of petroleum jelly on the butyl tape between the tape and the nut and the nut will spend on perfect the beetle tape will stay in place.
Put shower floor pads over drain holes when moored to keep clear
I did not silicone the threads, I just siliconed the cockpit side flange.
The most important thing is sealing the plywood of the transom with epoxy or something. Of that gets wet over time it would rot the wood. Keep in mind the scuppers are out of the water 99.99% of the time.
Hell yes it dose 🤙🏻thanks man for help yeah the stock ones suck
After watching a video like yours, I did the same project on my Catalina 22 8+ years ago. Last summer, I decided to just duck tape over the drain holes for the winter because I was sick and tired of cleaning the cockpit drain tubes which as you know is never easy. Now I just let the boat cockpit fill with water over the winter and know that the transom drains are there. I drained out the water this spring in the cockpit -cleaned up the mess- and took off the tape. Why didn't I think of this before?
I think most boats with larger cockpits have too small of scuppers to drain the weight of the water out fast enough to prevent sinking if following seas or other wave swamping events occurred. Are there larger scuppers with internal flapper- type valves to prevent the sea from entering lower transoms allow the rapid drain?
Does the water not "pool" in the stearn of the boat because of the angle facing forward?
They sit far above the waterline and almost never back flow, and if they do it drains very quickly
Could you post a link for the fitting?

Will the sealant not fail due to the cockpit moving relative to the transom?
It should be flexible enough for years to come. If it fails it’s a 10 minute fix above waterline.
Another tip I found out that in a following sea I would get water in the cockpit from my scuppers, so I installed the rubber flaps from Amazon that lets water out but not in.
By the way that is a very nice boat, I have hull 8588.
What's your hull number?
Great idea.. I never got around to it. I sold the boat before I got to that project
Nice!. You siliconed the threads as well? TXS
No silicon on the threads. Just along the locking nut flange. Remember this sits above the waterline so it’s not under any kind of pressure.
"marine grade" silicone???? What? Did they put a picture of a sailboat on the tube??? LOL.....
Next time use SIKAFLEX....cost more, way better....it keeps expanding for a while after application and NEVER goes hard/brittle...doesn't attract dirt/goes black like silicone does.
Used it on boats and RVs....won't anything else now
