It fits the standard 6 inch by 6 inch seat pattern, spins smooth and quiet in both directions, and comes with stainless hardware. It's a simple, affordable way to replace a worn swivel or rig up a new seat.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Attwood 75018 is the EZ Mount seat swivel, the part that sits between your pedestal post and the seat itself and lets the whole seat turn a full 360 degrees. It's a large base finished in black with stainless steel hardware. And it's a swivel-only unit, which means it spins but doesn't slide fore and aft. If all you want is for the seat to rotate, this is exactly the piece you're after.\u003c\/p\u003e\n\u003cp\u003eFitment is the first thing to check. This one is built for the most standard 6 inch by 6 inch seat hole pattern, the common four-bolt square you'll find on the bottom of most boat seats. If your seat bottom matches that pattern, this drops right in. We see it used most on center consoles in the 17 to 23 foot range, aluminum fishing boats, and runabouts where you want to spin the helm chair or a fishing seat around to face the cockpit. On a narrow bench seat, the large base can overhang the edges a little, so measure your seat pan before you order. And if you're replacing an existing swivel, take a quick look at the old bolt spacing first, since not every older pedestal top uses the same square pattern.\u003c\/p\u003e\n\u003cp\u003eHere's what swivel-only means in practice. The base handles rotation and nothing else. It won't move the seat forward or back for legroom the way a slide would. So if you need both rotation and fore-aft travel, you'd pair this with a separate seat slide. But for most boaters who just want the seat to turn, keeping it simple with a swivel-only base means fewer moving parts and less to go wrong.\u003c\/p\u003e\n\u003cp\u003eThe swivel runs on a self-lubricated bearing, so right out of the box it turns smooth and quiet. It's a non-locking design. That means it spins freely through the full 360 in both directions instead of clicking into fixed detents. That's exactly what you want when you're fishing and following a fish around the boat, or swinging around to grab something out of the cooler behind you. If you'd rather the seat hold a fixed position when you're running in a chop, some folks add an aftermarket detent or lock pin. Out of the box, though, it's a free spinner.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward. Bolt the base down to your pedestal top or deck plate, then bolt your seat to the top of the swivel. One tip from experience: on thin fiberglass or a thin aluminum deck, back the mount up with a quarter-inch aluminum or plywood backing plate. That keeps the base from flexing under your weight and spreads the load. The hardware that comes with it is stainless. If the black powder coat chips around the bolt holes during install, hit it with a little touch-up paint right away so it doesn't start to corrode.\u003c\/p\u003e\n\u003cp\u003eOn maintenance, don't overthink it, but don't ignore it either. Even a self-lubricated swivel lives a hard life in salt air. Give it a shot of marine grease every few months and it'll keep turning smooth for years, and a quick freshwater rinse after a salty day out never hurts. If you run brackish or salt water a lot, the included 304 stainless hardware holds up fine, but stepping up to 316 stainless bolts buys you extra corrosion resistance in the long run. Freshwater boaters can run it as it comes and not think twice.\u003c\/p\u003e\n\u003cp\u003eIt's a simple, honest piece of gear. If your old swivel has gotten gritty or finally seized up, or you're rigging a fresh seat and just need it to turn, the Attwood 75018 is an easy, affordable fix. Match it to a standard-pattern seat, bolt it down, and you're back to spinning freely.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e360 degree rotation on a self-lubricated bearing for smooth, quiet spinning right out of the box\u003c\/li\u003e\n  \u003cli\u003eFits most standard 6 inch by 6 inch seat hole patterns, so it drops onto common four-bolt seats\u003c\/li\u003e\n  \u003cli\u003eSwivel-only design keeps it simple: rotation without fore-aft slide and fewer moving parts\u003c\/li\u003e\n  \u003cli\u003eLarge base gives a stable footprint for helm and fishing seats on center consoles and aluminum boats\u003c\/li\u003e\n  \u003cli\u003eBlack powder-coated finish with stainless steel hardware for marine corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eNon-locking free spin turns a full 360 in both directions, ideal for following a fish around the boat\u003c\/li\u003e\n  \u003cli\u003eEZ Mount bolt pattern makes swapping out a worn or seized swivel a quick job\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Attwood Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat seat hole pattern does the Attwood 75018 fit?\u003c\/summary\u003e\n    \u003cp\u003eIt's built for the standard 6 inch by 6 inch four-bolt seat pattern, which is the most common pattern on boat seat bottoms.
