Lenco 20974-001 Limited Space Trim Tab 4x12 Stainless

This is the Lenco Limited Space trim tab, a single 4 inch by 12 inch tab cut from 12-gauge stainless steel. It's the tab you reach for when your transom doesn't have room for a full-size setup. Same Lenco engineering, shorter footprint. If you're replacing a bent or corroded tab on an existing Limited Space rig, this is the matching size.

Not every boat has a wide open transom. Twin outboards, a swim platform, a jack plate, a kicker bracket, all of that eats into the space where a trim tab wants to live. Lenco built the Limited Space line for exactly that problem. The 4 inch projection keeps the tab tucked in close, and the 12 inch span still gives you real lift where you need it. On smaller skiffs, bay boats, and tight-transom center consoles, this is often the only tab that fits without fighting the rest of your rigging.

The tab itself is 12-gauge stainless steel. That gauge matters. Trim tabs live their whole life half-submerged, slapped by spray, and loaded hard every time the boat comes up on plane. Thin material flexes and fatigues. Stainless at 12 gauge holds its shape under that load and shrugs off salt far better than mild steel or thin aluminum. You get a tab that stays flat, stays strong, and keeps working season after season.

Here's what a good set of tabs actually does for you. They make the single biggest difference in how your boat rides. Drop the tabs and the bow settles, the hull planes sooner, and you burn less fuel getting there. They knock down porpoising, level out a boat that lists from uneven weight or a crosswind, and give you a drier, smoother ride in a chop. Lenco runs their tabs on a ballscrew actuator, which is more powerful than a typical hydraulic ram and responds the instant you touch the switch. That instant response is what makes fine trim adjustments feel natural instead of laggy.

Installing a Lenco tab is straightforward if you've done any transom work. The tab bolts to the hull along the top edge and connects to the actuator that drives it up and down. Because Lenco uses an electric ballscrew instead of a hydraulic system, there's no pump to mount, no lines to bleed, and no reservoir to keep topped off. For a replacement, you're often reusing the existing actuator and mounting holes, which makes this close to a bolt-in job. Deburr any cut or drilled edges, bed everything in a quality marine sealant, and torque the fasteners evenly so the tab sits flat against the hull.

This listing is a single tab, not a pair. That's the honest way to sell a replacement part. If one side of your setup took a hit off a submerged log or finally rusted through at the hinge, you replace just that side and keep the good one. Buy two if you're doing a fresh install or refreshing both sides at once. Either way you're getting the genuine Lenco part sized to drop into the Limited Space geometry, so your trim stays balanced left to right.

Who's this for? Owners of smaller powerboats where a standard tab simply won't fit the available transom real estate. Think aluminum jon and mod-v hulls, fiberglass bay boats in the 16 to 22 foot range, tiller and console skiffs, and any rig where outboards, brackets, or a platform crowd the transom. If your boat came with Lenco Limited Space tabs, or you added them and love how the boat rides now, this keeps that setup running. Trim tabs are one of those upgrades you don't fully appreciate until one stops working and the boat starts leaning or plowing again.

One thing worth doing before you order. Pull your old tab, check the mounting pattern and the actuator connection, and match them to this 4 by 12 Limited Space size. Lenco part number 20974-001 covers this exact tab. If you're not sure whether your existing hardware matches, or whether you need the actuator too, give our crew a call. We'd rather spend two minutes on the phone than have you wait on the wrong part.
