When I bought my boat, it did not have a live well, but it did have a raw-water washdown that I never used. I got a round 15-gallon plastic tub and used a utility knife to cut a hole about halfway up the side. In the hole I mounted and sealed a PVC nipple to which I hooked up the washdown hose. I then cut two other holes higher in the sides of the tub for drainage and inserted and sealed two PVC nipples with downward pointing spouts. If I have bait such as shrimp that try to jump out of the well, I throw a piece of weighted netting over the top of the tub. The tub is removable for easy cleaning and I use it to transport frozen bait or food and gear to and from the boat.
