I own a '99 268 Islander with twin 200 yamahas. Any advice on how to convert an existing baitwell (with drain) into a livewell? I have rigged temporarily the salt water washdown with a hose directly into the baitwell with a 14" pipe into the drain for the overflow. This seems to work ok, but not real neat, and I lose a lot of water when underway. I am aware of aftermarket kits, but am wary of another thru-hull.Any advice is greatly appreciated.
