I ordered the parts from McMaster-Carr, a great place to get just about anything you need. Here are the parts I used:UncleTork wrote:What size pipe fitting is it?
Where did you find it in stainless steel?
Is your plug just a standard boat drain plug?
#4452K675 Type 316 Stainless Steel Threaded Pipe Fitting, 3/4 Pipe Size, Locknut, 150 PSI 2@$6.62
#4452K171 Type 316 Stainless Steel Threaded Pipe Fitting, 3/4 Male X 1/2 Female, Hex Reducing Bushing, 150 PSI 1@$6.16
#9191T38 Quick-Snap Expansion Plug with Stainless Steel Handle, for 13/16 Pipe Size, Stainless Steel 1@$11.85
I put 3M 5200 around the opening in the boat, and on the outer threads of the bushing. I've ground down the inside of the bushing so it's smooth (removed the threads) and the plug is still a little tight, so I'll have to grind out a little more. Instead of the 13/16" plug, you might want to try the next size down, 3/4".
