I've removed the old thru hulls and sanded down some 3/4" Schedule 40 white PVC pipe until it fits nicely in the the transom drain holes> BUT the drain plugs are 1". Stores and catalogs only sell 1/2" plugs for live wells and 1" and larger for transom drains. How have others made them fit? Have you whittled the rubber on the drain plugs or should I ream the pipe with a Dremel tool? Sorry to revive a topic which has been discussed but I DID already look for an answer.

While there pick up a tube of 5200 Fast Cure. (24 hours) cut the tube square about 1/4" long, Coat the tube, stick, it in the cleaned out hole in the boat, and clean up the excess caulk with a wet finger, and then some acetone, and it will be there forever.

Or should I have looked at electrical conduit? Maybe because I live in an area where frozen pipes could be a concern they don't stock it? Who would use a thin wall pipe on their plumbing? Would white PEX pipe work?I did get the Fast Cure and got the old tubes out and had hoped to complete this project today. I did start thinking about replacing the rubber stopper part of the drain plug with a 3/4" one from a labratory supply place. A #3 1 hole stopper would work. Not that I have any idea where to get lab supplies locally.

Once upon a time I had to make a drain plug fit a hole what I did was: take the drain plug apart (you have to force the issue because the retaining washer does not want come off reshape end of the stud and it will), I then threaded the drain plug onto a long bolt added a washer and a nut ( the bolt acted as a mandrel), I put that into a drill press and turn the plug down to size with a rasp, file and finished with sand paper, I cut the grooves back in the plug with a red hot steal comb. It was unnecessary work but it got the job done. I know this is not what you are wanting to do nor would I suggest it since you have the opportunity to find the right tube, just useless info I like to throw out every now and then. 1963 13' Sport 50hp Evinrude Maintaining a level of sanity that is socially acceptable

(Outside Diameter) but, 3/4" I.D., I searched "High" and "Low", did extensive web searches and they do NOT make a "Drain plug" that fit's a 3/4" "I.D." drain tube, it does'nt exist in this part of the world. What DOES exist though is a 3/4" "LIVE BAIT WELL PLUG" (Marine store), it fit's perfectly (adjustable too), and it takes up "LESS" room, making it easier to work on the "Bilge Pump" (if you have one). Might even fit the sched. 40 PVC They are sold in a 2 pack, so I have an extra one if you need it, lemme know, I'll get it out to you. Just did a search: West Marine has them, part number (wm9531021) 3/4" live bait well plug by "Moeller", $13.99, 3/4" I.D. Edited by MW on 06/07/09 - 3:54 AM Matt

Its main purpose is for irrigation, because pressure inside a pipe is non existent in irrigation lines, so the pipe does not have to be as thick as schedule 40. Normal size marine drain plugs fit perfect. I have two different types and they both fit perfectly. I have the lever handle type and the screw in type with the T handle. If this is a problem send me your mailing info, and I`ll send you a piece. For about $4 I can buy 5 ft. of pipe, enough for many drain tubes. Rich

Maybe a different manufacturer of the "PVC" pipe ? I think the PVC stock that I used was rated for "Electrical". I'm just glad those "Rotted" drain tubes are replaced, they were really starting to bug me, I hope they don't crack if they get clogged and water freezes in them during "Off season" winter storage, you know how rain water likes to get under the tarp.

AGAIN: USE 3/4" PVC THINWALL PIPE. IT IS NOMALLY USED FOR UNDERGROUND IRRIGATION SYSTEMS (SPRINKLER SYSTEMS) IN YOUR LAWN. THE REASON IT IS THINWALL IS BECAUSE IT NEVER HOLDS PRESSURE, AND IT IS MORE FLEXABLE THAN SCHEDULE 40, SO IT CAN BE LAID IN CURVED TRENCHES TO ACCOMATE YOUR SPRINLER SYSTEM. THIS IS NOT ROCKET SCIENCE!! iT WORKS GREAT FOR DRAIN TUBES. i JUST DID THIS LAST MONTH ON ONE BOAT AND TWO YEARS AGO ON MY 13 FOOT WHALER. Rich

The pointy end goes up, the finned end goes down, and you light off the little thing under the fins. Simple enough when you understand it. Not so with drain tubes apparently LOL Rich

Member Personal Page Posts: 100 Comments: 7 Joined: 01/17/09	NOW you tell me. Went back to Big Orange and they had no idea what thin wall pipe was. So I Dremelled the Schedule 40 carefully until I could get the drain plug in. It's now cut and glued in. Thanks everyone. At least the next confused person doing a search will see it's pvc pipe for sprinklers. I am happy I completed a project this weekend and the boat can now get wet. BTW let me mention that every spot of foam peeking through and inside the transom the boat is DRY. It's been out of water under cover for at least three months now.

The thicker the wall, the more P.S.I it will handle. I use 200 P.S.I. white pvc pipe for the console rod holders. It has a much thinner wall than the schedule 40.
