through hull drain tubes in the floor

[Bushwacker]

. . . I can't imagine scuppers that run through the bottom work all that well either. Eric

That's because your missing one small but important detail. There are small wedges attached to the hull just in front of the scupper tubes which create SIGNIFICANT suction. It pulls the water out much faster than just depending on gravity!

I think I had temporarily removed them for better access when flaring the end of tube, so that's why you didn't see them in photos in my old post.

Also, you don't necessarily have to buy an expensive flaring tool. I used some threaded rod, nuts & washers and some tapered sockets I had to get the flare started, then finished with ball peen hammer. Maybe not as pretty as using a tool, but it worked! One problem with those plastic tubes is that they will eventually crack if enough UV gets to them.

I had replaced these on an older Whaler I had. A tow ball works great also. I had to "anneal" the brass tube by torch heating and quench in water usually twice. This prevents splitting when flaring.

I have no evidence on my boat that anything ever went through the bottom of the hull except the drain for the baitwell. I will search harder i guess.

The thru-the-bottom scuppers may have been unique to the Potter models, about 1970-79. Not sure of configuration post-Potter.

mine is a 79. i know it had them at one time because the plastic thru deck fittings are ther but have no tubes or hoses attached and the fittings have been filled with 5200

FELLOW SHIP and you other people that have changed the deck drains come aboard with some help!

Help? Go to the search function and type in self bail scuppers Then check older than 1 month. Next take your laptop and sit on the can for the next few hours reading and looking at pictures [img]/forum/images/graemlins/tongue.gif[/img]

if your floor drains are like mine, it was pretty easy to get them out and put new ones back in. i tried to use PVC but didnt like it. i would have had to get new plugs and stuff. so i went ahead with the brass and epoxy and have had no problems or leaks yet. thats been probably 1.5 years ago.

Bush I'm going to have to start paying you for ideas. I would have never thought I could taper the tubes like the way you described. Definitely hit you up when I attempt that. I have to watch a couple of old mcgyver episodes to gain some confidence first. LOL

In reference to Greno's qoute. I do have a major problem when those floor drains are unpluged. If your maintaining your station and you walk to one side of the boat the drain hole in the floor drops below the water line and begins to pour onto the deck. I always thought that was kind of a weird reaction if they weren't meant to be plugged all the time.

has anyone else had the flooding problem with the drain dropping below the water line when you walk to one side of the boat?
