Attwood SP-15900 Jon Boat Seat Mount | Tilt-N-Slide

Attwood's been building marine hardware for over a hundred years, and the SP-15900 is one of those parts that just does its job without any fuss. It's a bench-style seat mount set made for jon boats, and it ships with the aluminum seat plate plus a pair of 15-inch slide rails. Bolt the rails down, drop the plate on, and you've got a real mounting point for a standard boat seat where before you had nothing but a bare aluminum bench.

The reason folks reach for this one is the Tilt-N-Slide setup. The seat plate rides on the rails, so you can slide the seat forward and back to find the position that works. Casting up front? Slide forward. Running the tiller all day? Slide back and give your legs some room. And when you want the deck clear for loading gear or standing to fight a fish, the tilt lets you fold the seat down out of the way.

About those 15-inch rails. That length gives you a solid range of slide travel while keeping the footprint tight, which is exactly what you want on a narrow jon bench. If your layout calls for more fore-and-aft range, Attwood offers the same style mount on longer 30-inch rails. But for most bench jons, 15 inches hits the sweet spot between adjustability and not eating up your whole seat base.

The plate and rails are aluminum, so the set stays light and won't rust out on you the way plated steel does. That matters on a boat that lives wet. It keeps the weight down too, which you'll appreciate on a car-topper or any jon you're loading and unloading by hand.

Before you order, throw a tape measure across your bench. You want enough flat, solid width to land both rails and get bolts through into something that'll actually hold. Most factory jon benches handle it fine. If your bench is ribbed or hollow underneath, plan on a backing plate so you've got real material to torque against.

Installing it is straightforward if you've turned a wrench before. The rails bolt down to your bench or floor. We'd run marine-grade stainless hardware sized to your bench, and on a thin aluminum floor it's worth adding fender washers or a backing plate underneath so the bolts don't pull through when you sit down hard or stand up quick. Take your time marking the holes so the rails sit square and the plate slides clean.

Now, this is the mount, not the seat. It's built to take a standard bench-mount boat seat with the common bolt pattern, so you supply the seat you like and this gives it a home. Low-back, high-back, folding, that's up to you and your back. The SP-15900 just handles the mounting and the sliding.

Plenty of anglers run a pair of these to turn a bare utility jon into a proper two-seat fishing rig. One forward for working the bank, one aft at the helm. Because the plate slides, you can trim each spot to whoever's sitting in it, which beats a fixed pedestal that never quite lands where you want it.

Maintenance is about as easy as it gets. Aluminum shrugs off freshwater, and a quick rinse after a saltwater day keeps the slide action smooth. If the rails ever feel gritty, wipe them down and they're back to sliding clean. No motor, no electronics, nothing to fail. Just a mechanical mount that keeps working season after season.

So who's this for? Anybody with a jon boat who's tired of perching on a cooler or a bare bench. Whether you're duck hunting, running trotlines, or chasing bass on a farm pond, a real seat that slides and tilts makes a long day a whole lot more comfortable. It's a simple, honest piece of gear, and at this price it's an easy upgrade to a boat you actually use.
