Uflex USA B184 Side Mount Single Lever Control with Power Trim

The Uflex USA B184 is a side mount engine control built for outboard boats. It's the box that bolts to the side of your console or dash and gives you one lever to run everything: forward, neutral, reverse, and throttle, all in a single smooth motion. Push the handle forward and you shift into gear and add throttle in one move. That's what "single lever, dual action" means, and once you've run a boat this way you won't want to go back to separate shift and throttle levers.

What makes the B184 stand out in the Uflex side mount line is the power trim switch built into the handle. You keep your hand on the control and trim the engine up or down with your thumb. No reaching for a separate button on the dash while you're trying to hold a heading in a following sea. If you run an outboard with power trim and tilt, this is the control that keeps everything under one hand.

Shifting is clean and deliberate. The handle has a pull-out neutral warm-up feature, so you can pull the grip out and rev the engine in neutral to warm it up on a cold morning without ever putting the boat in gear. There's a neutral-start interlock too, so the control has to be in neutral before the engine will crank. Little things, but they're the difference between a control that feels like a factory rig and one that fights you at the dock.

Cable compatibility is where a lot of folks get tripped up on a repower or a helm swap, so let's be clear. The B184 works with MachZero cables and most standard 3300-series control cables, which covers the vast majority of outboard setups on the water. If you're replacing an old control, measure your existing cables and match the length, and you're usually good to go. The dual-action design pulls and pushes the cable through its full travel, so you get positive shifting and full throttle range as long as the cable is routed with smooth bends and no binding.

Who's this for? Owners of outboard-powered center consoles, walkarounds, bay boats, and runabouts who want a proven side mount control at a fair price. It's a great choice on a repower when the old control is sloppy or the trim button has quit, and it's just as at home on a fresh rigging job. Side mount is the right pick when your helm has the room on the side of the console for the control box, which is most single-engine and many twin outboard layouts.

A few install notes from folks who've rigged these. Route the cables so the lever gets its full travel without the cable jacket binding at a tight bend. Give yourself a gentle sweep instead of a hard elbow behind the dash. Secure the trim switch wiring away from the pivot so it doesn't chafe as the handle moves, a couple of zip ties do the job. And in salt air, hit the trim button contacts with a little dielectric grease at install. The trim contacts are the first thing corrosion goes after, and a dab of grease keeps that button crisp for years. If you're running MachZero cables, set the preload with a quarter-turn adjustment so you don't get any neutral creep once everything's connected.

Uflex USA has been building steering and control gear for boats for a long time, and it shows in the feel of this unit. The detents are positive, the trim switch is right where your thumb lands, and the whole thing is designed to take spray and sun the way marine gear has to. It's honest equipment that does its job every time you turn the key. Bolt it up, run your cables, wire the trim, and you've got a clean, one-handed helm that any boater can run confidently.
