{"product_id":"edson-powerknob-proseries-stainless-boat-wheel","title":"Edson PowerKnob ProSeries - Stainless","description":"\u003cp class=\"nvn-hero\"\u003eThe Edson PowerKnob ProSeries is the classic stainless steering knob, one solid grip that lets you throw the wheel lock-to-lock with one hand. Turned from 316 marine stainless and riding on two rows of Delrin ball bearings, it clamps tight to your rim yet spins butter-smooth. If you dock single-handed, you'll wonder how you steered without it.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've ever tried to spin a boat wheel hand-over-hand while backing into a tight slip, you already know why a PowerKnob earns a spot on the helm. The Edson PowerKnob ProSeries gives you one solid grip to grab, so you can throw the wheel lock-to-lock with one hand and keep the other on the throttle or a dock line. It's the kind of accessory you don't think about until you've run a wheel without one. Then you won't go back.\u003c\/p\u003e\n\u003cp\u003eEdson has been building steering gear for a long time, and this knob is the classic. It's turned from 316 marine-grade stainless, the same alloy you want on anything that lives in salt spray. The polished stainless finish looks right on a teak-and-bronze sailboat helm or a modern powerboat dash. But the real story is inside. The knob rides on two rows of Delrin ball bearings, and Edson's design isolates the clamping pressure from the bearing pressure. In plain terms, that means you can crank the strap down tight enough that the knob never walks around the rim, and it still spins butter-smooth. A lot of cheaper knobs make you choose between grip and spin. This one doesn't.\u003c\/p\u003e\n\u003cp\u003eIt fits any stainless or aluminum wheel rim between 5\/8 inch and 1-1\/8 inch in diameter, which covers the vast majority of destroyer and standard wheels out there. Measure your rim before you order. That's the one number that matters, and if you're between sizes it's worth pulling out the calipers. Once you know it fits, the install is about as easy as boat projects get. You strap or bolt it onto the rim, snug it down with the included hex wrench, and you're done in about five minutes. No wiring, no drilling on most wheels, no drama.\u003c\/p\u003e\n\u003cp\u003eWhere does it shine? Docking, mostly. Single-handed sailors love these because you can hold a line or a fender in one hand and still steer with authority. On a powerboat, it makes quick corrections at low speed effortless, spinning the wheel hard-over to hard-over without shuffling your grip. Sailors running a big destroyer wheel on a 28 to 35 foot boat get a real mechanical advantage out of it too, especially when you're fighting weather helm and want to make a fast course change.\u003c\/p\u003e\n\u003cp\u003eBecause it's built for all-weather use, you can leave it on an open helm year-round. Rain, sun, spray, it doesn't care. The stainless races and Delrin bearings shrug off the wet, and there's no grease to wash out or plastic housing to go chalky in the UV. That matters on a center console or a sailboat cockpit where the wheel sits out in the weather every single day.\u003c\/p\u003e\n\u003cp\u003eA couple of honest notes. On a large, heavy powerboat, some folks find the knob spins so freely that they'd rather have a touch of drag. If that's you, a simple friction washer sorts it out. And like anything that takes a beating in rough water, it's worth checking the clamp every so often and re-snugging it, because a knob that's been slammed lock-to-lock for a season can work loose. A dab of threadlocker on the hardware buys you peace of mind. The stainless finish will pick up fingerprints, so keep a little metal polish in the console if you like it showroom-bright. None of that is a knock on the knob. It's just what to expect from a hard-working piece of helm gear.\u003c\/p\u003e\n\u003cp\u003eThis isn't the right part for a tiller boat or a small outboard steered off the motor. You need a real wheel with a rim in the fitment range and enough clearance to swing the knob. If you've got that, the PowerKnob is one of those small upgrades that punches way above its price. Edson backs it with a 25-year warranty, which tells you how they feel about it lasting. We've put these on plenty of customer boats, sail and power both, and the feedback is always the same. Wish I'd done it sooner.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eTurned from 316 marine-grade stainless steel, stands up to years of salt spray and open-helm weather\u003c\/li\u003e\n  \u003cli\u003eRides on two rows of Delrin ball bearings for a fast, butter-smooth spin\u003c\/li\u003e\n  \u003cli\u003eBearing design isolates clamping pressure from bearing pressure, so it grips the rim tight and still turns freely\u003c\/li\u003e\n  \u003cli\u003eFits any stainless or aluminum wheel rim from 5\/8 inch to 1-1\/8 inch diameter\u003c\/li\u003e\n  \u003cli\u003eStraps or bolts onto virtually any steering wheel, no drilling on most rims\u003c\/li\u003e\n  \u003cli\u003eAbout a 5 minute install, hex wrench included in the box\u003c\/li\u003e\n  \u003cli\u003eAll-weather construction with no grease to wash out or plastic to chalk in UV\u003c\/li\u003e\n  \u003cli\u003eBacked by a 25-year manufacturer warranty\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 Edson 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 wheel sizes does the PowerKnob fit?\u003c\/summary\u003e\n    \u003cp\u003eIt clamps to any stainless or aluminum wheel rim between 5\/8 inch and 1-1\/8 inch in diameter.
