Bennington SX20 Pontoons For Sale

The Bennington SX20 is a 20-foot pontoon boat rated for a 10-person maximum capacity, built on either a twin-tube or tritoon hull. It accepts outboard power up to a Yamaha 90 horsepower, with smaller options such as a 20 horsepower used where local state park rules require them, and a Yamaha 50 horsepower four-stroke is one common setup. The pontoons are commonly upgraded to 25 inches in diameter for added stability, and the SX series received a redesigned interior a few years back. It suits buyers who want a compact family pontoon that still carries a dedicated fishing rear with swivel seats and a livewell.

On the tritoon version, the SX20 comes with Bennington's Sport Performance System, which adds lifting strakes on the inner faces of the outer toons and both sides of the center toon, an under-deck wave shield, and a SeaStar hydraulic steering system. That package pairs with a 32-gallon fuel tank and a reinforced transom. A saltwater series anode package is available, and the boat can be matched with a tandem-axle trailer with brakes on both axles, a winch jack, and a spare tire. Some hulls are fitted with Sea Legs.

The helm centers on an SX-series captain's chair that swivels, reclines, and slides fore and aft, set behind a tilt steering wheel. Gauges cover trim, tachometer, and fuel, alongside the accessory switches and the livewell control. An inlaid Garmin unit reads water depth, water temperature, GPS speed, and bottom structure, and doubles as a fish finder. The Kicker AM/FM stereo runs Bluetooth, USB, and audio inputs with a 12-volt accessory plug, and the four illuminated Kicker speakers light up at night.

The deck layout comes in several floor plans, including a family-front fishing-rear arrangement and a quad bench with seating in all four corners and an extra-long port bench. Every bench lifts for storage underneath, with poles for the included mooring cover and a Bennington cooler stowed below. Portable cup holders with side phone pockets move to any seat, and a two-piece kidney table mounts to a floor post or stows under the helm. The bimini top extends 10 feet of shade over the console seating area, and optional LED accent lighting and LED docking lights are available. A privacy enclosure folds out for changing or a porta-potty, and the sunbed lifts for a large storage compartment.

The fishing rear carries two deluxe bass swivel seats upgraded from the standard chairs, a livewell with its dash-mounted fill switch, rod holders, and a rear boarding ladder behind a gate. A ski tow bar is included and mounts once the outboard is installed; some models add an extended aft deck and an upgraded ladder with an extra step. Flooring is woven vinyl or seagrass in colors matched to the exterior, available in schemes such as Monaco blue with white accent, midnight black with lime green, and sunset red.

Build quality rests on through-bolted crossmembers and side panels wherever possible and thicker, wider aluminum channel frames. The pontoons, frame structure, decking, and seat bases carry a lifetime warranty to the original owner, with everything else covered for 10 years, including electronics like the Kicker stereo without proration. Simtex upholstery is used throughout and stays a few degrees cooler in the sun than standard vinyl. When weighing a Bennington SX20 pontoon boat for sale, confirm the hull type, outboard horsepower, and which floor plan and options are fitted, since pricing and equipment vary by configuration.
