I tried them, thanks. They didn't have one either.
Here's what I found out. In 2000, they used a black nylon/plastic fitting, 6" total. Unfortunately, the threads end before the they get through the liner. In 03, 02, and probably 01, they used a 6" brass/bronze fitting that's threaded to the top. They put a tailpiece on that which converts from threads to a barbed hose fitting. The opening is right around 4" deep.
Those brass/bronze pieces are $40 for the 6" piece and the catalog shows $50 for the tail piece.
What *I* ended up doing is taking the nylon/plastic piece, cutting it down to length needed to make the rest fit tight. I added a threaded to threaded fitting that I got from West Boats, as well as a male thread to hose fitting.
I used my Dremel to take the molded-in "nut" on the female-female threaded fitting (so it'd fit into the hole). I had to increase the hole in the liner to 2 1/8". The hole in the hull is 2". I threaded the nut for the original 6" fitting onto the male-male adapter (to get the washer/nut combo instead of just the nut on the adapter).
So, in the end, I have a silicon sealant between the hull and the flange at the bottom and more sealant between the washer/nut combo and the liner. The reason is that there's floatation foam in there and it doesn't need to get wet.
Now, it's time to get to the lake and see if it holds water.
