Cobalt R4 Boats For Sale

The Cobalt R4 is the smallest model in Cobalt's R series, a 24-foot 3-inch sterndrive bowrider built for day boating and lake water sports. It carries an 8-foot 6-inch beam, a 50-gallon fuel tank, and seating for up to 13 people or roughly 2,100 pounds. There is no enclosed head, which keeps the layout open for socializing but is worth weighing if you plan longer days away from shore. As a 2026 model it has been priced around $155,284, and used examples for sale trace back to that figure. The deep-V hull absorbs chop and the under-9-foot beam keeps the boat trailerable behind most SUV or four-wheel-drive tow vehicles without width restrictions.

Power comes from a single sterndrive with options spanning 300 to 430 horsepower, drawn from Mercruiser, Volvo Penta, or Cobalt's Monsoon marinized small- and big-block engines. Common builds run a 350-horsepower setup, whether the Monsoon 5.3-liter, a Mercury 6.2-liter MerCruiser, or a Volvo V8. Top speed lands between 47 and 52 mph depending on engine choice. At a typical cruising pace the R4 returns roughly 1.75 to 1.9 miles per gallon, giving the 50-gallon tank a practical range near 100 miles, less when running hard. Draft measures 19 inches with the drive up and 36 inches down, and dry weight including the engine is 5,290 pounds.

The helm centers on a dual Garmin glass cockpit, configured as two 10-inch displays or paired Garmin 8610 touchscreens handling navigation, digital gauges, engine diagnostics, and RGB lighting control, which is standard on the R series. The dash uses push-button LED-lit switching, a leather-wrapped stainless steering wheel, and a wireless phone charging mount, with USB receptacles throughout. Audio runs through a Fusion head unit with a subwoofer upgrade and JL Audio speakers, including tower speakers. A Lenco trim tab package, digital throttle and shift, and active trim control simplify handling for newer captains, automatically adjusting trim in chop and planing conditions.

The cockpit and transom are built around versatility. The aft lounge converts between a forward-facing bench, an aft-facing rumble seat in a back-to-back setup, and a full-down sun pad, while a flip-up swim step folds out for water access. A heater system with a retractable tube and a bow door that folds open against the windshield extend the boating season into cooler weather. Self-bailing storage compartments double as iced coolers that drain through the bilge, a transom shower and transom stereo remote sit at the stern, and the boat carries 12 cup holders. A heavy-duty aft pylon and a folding arch with bimini support tubing, skiing, and wakeboarding; clearance is 97 inches with the tower up and 58 inches folded down.

Storage is a defining trait, with deep in-floor lockers in the bow and midship, a ski locker, Gold Wing-style bow compartments, and hydraulic bow hinges that lift the cushions with the pull of a handle. The bow seating area is one of the deeper sections in the 24-foot class, finished with teak inlay on the cockpit table and stainless steel hardware throughout. A dual battery system with a maintainer is standard on the R series. The Volvo Penta package carries a five-year engine and drive warranty, and closed-cooling engines with a heat exchanger make the R4 usable in brackish or salt water without raw water entering the engine.

The R4 is the outdrive version rather than the dedicated R4 Surf, so it has no ballast or wake gate and no inboard surf wake. The tradeoff is sterndrive maneuverability that makes docking and tight turns easier, lower maintenance, and a lower price than a dedicated surf boat. For families wakeboarding, water skiing, tubing, and cruising in comfort, the Cobalt R4 covers the brief while keeping the timeless interior finish Cobalt is known for.
