I'm selling the fish box that sits under the hatch in the the aft cockpit of the 34C/36C. Mine came out of my 2005, but it will fit in the 2004 and (I believe), all the newer years. It has a fitting on the bottom where water can be pumped in along with the hose that connects it to the water pump (not included).
In the pictures below, you'll see dust, a few minor blemishes and rust stains which should all easily come out. It's in great condition as it has been in my basement for 14 yrs.
This is of course pretty large, so you would need to be able to come pick it up in North Kingstown, RI. I have no way to ship this thing.
Feel free to contact me if you have any questions.
