T-H Marine 1-1/8 in 90 Degree Livewell Thru-Hull

If you've ever pulled up to the ramp with a well full of dead shad, you already know the problem this little fitting solves. The T-H Marine 90 degree thru-hull fitting is the head that sits inside your livewell or baitwell and turns a plain fill line into a moving, circular current. Water comes in through your 1-1/8 inch marine hose, hits the 90 degree head, and gets pushed sideways along the wall of the well instead of straight down. That swirl is what keeps bait alive.

Here's why that matters. Baitfish breathe easier in moving water. A steady circular flow keeps oxygen mixing through the whole well, and it stops the bait from bunching up in one corner where they stress out and burn through oxygen fast. Shad, herring, shiners, whatever you're running, they all last longer when the water's turning over. In hot weather or on a long run to the first spot, that difference shows up on the scale at weigh-in.

This is the 90 degree version, and it's built to mount below the waterline. That's the key. Down low, the head throws a strong horizontal jet that wraps the current around the inside of the tank. The head itself is low profile with a rounded face, so your bait aren't slamming into a hard edge every time the boat rocks. Delicate baits like it. If you've got a taller tank and want aeration up top instead, the same T-H Marine family offers a 45 degree head that mounts higher, but this short 90 degree fitting is the one you want for that fill-and-swirl job down at the bottom.

Fitment is simple. It fits standard 1-1/8 inch marine hose, which is the common size on most bass boat and bay boat livewell plumbing. It's a short thru-hull, so it seats cleanly through the tank wall without a lot of barrel sticking out into the well. You run your hose from the livewell pump to the fitting, clamp it down, and you're done. The barbed end grips the hose tight once you snug the clamp, and the smooth bore keeps water moving without choking down the flow. Keep a stainless hose clamp on the connection and you won't have to think about it again.

The finish is black, which disappears against a dark livewell interior and won't yellow or chalk the way cheap white plastic can after a couple seasons in the sun. It handles both saltwater and freshwater duty, so it holds up whether you're chasing largemouth on a lake or trout and reds in the bay. This is the kind of part you install once and forget about.

Maintenance is basically nothing. Rinse the well out after a saltwater day so salt doesn't build up around the head, and give the fitting a quick look each season for cracks or a loose clamp. There are no moving parts in the fitting itself, so the only real wear point is the hose connection, and a fresh clamp fixes that in two minutes.

So who's this for? Anglers who fish tournaments or just want their bait frisky at the end of a long day. It's also a smart upgrade if your current well runs a plain straight fitting and your bait keep dying on you. One thing to be clear about. This is a single fitting, sold on its own. It doesn't include hose, a pump, or clamps. If you're plumbing a well from scratch, you'll want to grab the hose and a livewell pump to go with it. But if you're replacing a cracked or missing head, this drops right in.

Simple part, big payoff. Get the water moving the right way and your bait shows up ready to fish.
