The Sea Ray SLX line sits at the top of the builder's sport boat family, above the SPX and SDX series, and spans the SLX 230, SLX 250, SLX 260, SLX 280, SLX 310, SLX 350 and the flagship SLX 400. The SLX 280 fills the five-foot gap between the 260 and 310, measuring 28 feet 8 inches length overall with a 9-foot beam and a 40-inch draft with the stern drive down. Because it runs over 26 feet, the 280 is yacht certified and can carry as many passengers as it has seating. Shoppers looking at a Sea Ray SLX 250 will find the same attention to detail in the hardware, including 316-grade stainless steel cleats screwed from the inside out over laminated backing material, and a stainless anchor on a proper bow roller.
The Sea Ray SLX 280 comes standard with a 350-horsepower Mercury MerCruiser 6.2L MPI ECT on a Bravo 3 drive, with an optional 430-horsepower 8.2L MPI ECT also available. With the 430, the SLX 280 topped out at 49.7 mph at 5,000 rpm, with best cruise at 3,500 rpm and 32.7 mph; at that speed a 15.7 gph fuel burn returned 2.1 mpg and a range of 219 statute miles on the 117-gallon tank while holding a 10% reserve. The Sea Ray SLX 350 is a large outboard-era bow rider running twin 350-horsepower Mercury petrol engines through Bravo Three drives, tied into the Axius system with Skyhook, and reached a top speed of 56 knots in test conditions.
The Sea Ray SLX 400 OB carries a length overall of 41 feet 11 inches, a beam of 12 feet 1 inch and a 45-inch draft, with an empty weight of 18,537 pounds. Powered by triple 300-horsepower Mercury Verado outboards swinging 16-by-18 props to 5,900 rpm, it topped out at 51.8 mph; best cruise came at 4,000 rpm and 32.9 mph, where a 34.8 gph burn returned 0.9 mpg and a 319-statute-mile range from the 375-gallon fuel capacity. It jumps on plane in about 4.8 seconds and reaches 30 mph in 9.5. Buyers weighing a Sea Ray SLX 400 for sale can choose 300 or 350-horsepower Mercury power and add a Seakeeper 3 on stringers already built to accept it.
Helm equipment is consistent across the range. The SLX 280 uses dual 9-inch Simrad displays, upgradable to dual 12-inch, paired with digital throttle controls, a Fusion head unit and a tilt-base steering wheel, with vessel functions managed through combined Simrad and Mercury screens. The SLX 400 steps up to dual Simrad Evo3s multifunction displays with the NaviOp system, controlling lighting presets, tank levels, battery readouts, active trim, cruise control and the Seakeeper from the dash. The 400 can also be optioned with the Fathom e-Power system, 22 kilowatt-hours of lithium-ion batteries that run air conditioning, electric grills and refrigeration, shedding non-essential loads as it nears 5% and recharging from alternators, generator or shore power.
Deck and cockpit layouts focus on social space and water access. The SLX 280 has a maximum cockpit depth of 39 inches, grab handles at every seat, a 68-by-42-inch sunpad, a 12-volt drawer refrigerator under the captain's chair, and a head compartment 49 inches high by 33 inches wide with a vacuum-flush toilet, sink and cabinet. An electrically deployable swim step extends 18 inches into the water, a feature the SLX 350 echoes with a full platform that drops below the surface for swimming and wakeboarding. The 350 adds an enclosed head with sink, a small cabin with an infill berth, and a galley with trash compactor and Isotherm fridge. Bow seating across the line accepts filler cushions to form sun lounges, and the Power Tower lowers electrically for low bridges, dropping the SLX 280 to 8 feet 8 inches of clearance.
Build quality is the recurring theme buyers cite when seeking used Sea Ray SLX boats for sale, since the hardware, laminated backing and upholstery hold up over many years. Teak is offered throughout the cockpit and swim platform alongside SeaDek and Infinity woven flooring, with interior palettes in Dune, Ivory and Stone. With bundles for entertaining, cruising and water sports, the SLX range scales from the SLX 230 and SLX 250 up to the SLX 400 OB depending on how many guests and how much range a buyer needs.
