I built this one for my previous boat. I had to raise it with a Starboard stand to get the drains over the transom in this SC. It keeps menhaden alive here in August all day with 700 gph pump. I can detail the design with better pics if you want if your building one. I just put a ratchet strap around it to two mounts that are just out of sight in this pic. The ball valve feed is kept out of sight when not in use. It works great but I would prefer a leaning post style.
