Need help with a small part on a Mariah Shabah 198SE. It is a through hull fitting that drains the under dash cooler. About 1 inch long with a barbed post (3/8" diameter). The flange is 5/8". It just pushes through the hull and the cooler hose slides on. The flange is broken and I cannot find a replacement part to save my life. I will attach a pic. Any help is greatly appreciated.

If you can't find one in 3.8", use a 1/2" fitting and adapt the hose to it. Of course, the exposed head would be much larger.

Of if you can use SS, then this one. Maybe paint the exposed part white.
