Darle,
You could use copper pipe of the diameter of your choice, and flange out one end with plumber's tools. I liked the ready-made flange on the chrome plated sink drain.
I slipped a backer plate of 3/8" thick sheet Lexan with a 2" hole over the small end of the pipe and snugged it up against the back of the flange and glued it in place. Then I cut a 1/4" sheet of Lexan into a circle the same diameter as the flange. I made a black gasket out of RTV silicone gasket making goo, from a tube. When set, I drilled 6 holes through the backer plate and the cover and tapped the backer plate holes for SS studs. I enlarged the cover plate holes slightly, and slipped the cover plate over the 6 studs, put on rubber washers, SS washers, and nuts to hold the cover plate snugly against the outside of the flange.
After installing a SubTech shaft seal in a 1/4" thick by 2" diameter circle of Lexan cut out with a hole saw, I glued the Lexan assembly into the small end of the pipe.
I can access the motor, universal joint, and shaft through the flange end cap. See picture from prior post.
I made a motor mount out of Lexan and rubber to isolate the motor from the pipe and absorb vibration.
Hope this helps.

Hi Art and Group ,

Well I bought a piece of sink drain pipe , the oly problem is,
the pipe is 1.5" diameter , not the 2.0" diameter pipe .
So I plan to cut some short pieces of the pipe for the 2
Johnson 12 Volt motors that I will be using . The 2 pieces
will be big enough to house 75% of each motor , I will build
a housing to attach to the tubes for the additional housing
area that will be needed and make the housing big enough
to allow for some needed air space for enternal cooling .
I will be using .030" thick brass sheet to make the additional
housing area .
Well off to work on the boat .
Thanks Art for your help with this project .
Do you have any other isdeals or tips to share ??

Darle :D
