Boat Brass Drain Tube

[mtgtool]

 I'm having a hard time finding 1-3/4" Brass Drain Tube for the floor drains. Can any one help me on this?  I'd like to say thanks for all the help giving on project.

Why 1-3/4" ?

I think they are 1 1/4 and just bought a 2 pack off ebay

That is the size of brass tub in there now.

And it's located where?
Photo perhaps?

I took a picture so you could see what I was talking about.  They are an 1 3/4" holes.  I cannot find the tubes already made up for the job.  I did find an 1 3/4 OD by 12" tubing and guess I'll have to make my own.  For the life of me I cannot figure out how to post the pictures (even with the instructions).  They are in My Photos.  Thank you Captain Bob and all of you

Here ya go.

Since you’re redoing your transom, you can make the holes whatever size you want.  Later Aquasport used 1” tubes.

Here’s a thought, don’t use brass tubes.  They all eventually develop stress cracks and allow water into the transom core.  You can simply epoxy PVC tubes through your transom.  The gray PVC sold for conduit is more UV resistant.

I like the PVC pipe idea.  That is easy to work with.  I believe that is the way I'll go.  Thank you

As long as your scuppers are above the waterline and you can find a way to plug the scupper in an emergency, you can go with whatever size scuppers you want.
