Sea Ray SLX 280: BoatTEST Review

Reviewed by Jeff Hammond

Overview

The Sea Ray SLX 280 Outboard represents the brand's top-of-the-line series, thoughtfully reimagined from the water up to emphasize luxury, innovative technology, and enhanced functionality for both entertainment and adventure. This model comes standard with dual 250 horsepower Mercury outboards paired with joystick piloting, available in black or white. Measuring 31 feet, 5 inches in length overall, with a beam of nine feet and a draft of 35 inches, the SLX 280 is designed to deliver a balanced combination of performance and comfort.

Power and Performance

Powered by dual Mercury outboards, the SLX 280 has a dry weight of approximately 8,053 pounds, with the demo model weighing around 9,500 pounds. Fuel capacity is 135 gallons, complemented by a 20-gallon freshwater tank. Performance testing revealed an economical cruise speed at 4,000 rpm, achieving 35.4 miles per hour and fuel efficiency of 2.1 miles per gallon, translating to a range of 249 statute miles with a 10% fuel reserve. At wide open throttle (6,100 rpm), the boat reached a top speed of 56.4 miles per hour. The vessel demonstrates quick planing even when fully loaded and promises a smooth, stable ride in various water conditions.

Cockpit and Exterior Features

The cockpit serves as the central social hub, featuring opposing seating arrangements that foster interaction among guests. Upholstery is crafted from high-quality, durable materials with intricate diamond stitch work and ergonomic design, including deeper seats with lumbar support and water-shedding capabilities. The captain's chair is notably wide at 39 inches, accommodating two people comfortably, swiveling to expand the social area, and equipped with convenient cup holders, USB ports, and a hidden inductive charger. Beneath the captain’s seat is a drawer-style 12-volt refrigerator, a rare and clever space utilization for a boat of this size. Additional cockpit amenities include a locking glove compartment, a vacuum-flush head with sink and storage, and a large storage locker in the sole designed to accommodate long items such as skis.

Helm and Technology

The helm station is equipped with joystick piloting for outboards, digital throttle controls, and a tilt steering wheel wrapped in premium material. Dual 12-inch multifunction displays provide comprehensive navigation, vessel, and engine information, while stainless steel tilt switches and active trim controls offer intuitive redundancy. The onboard audio system, developed in collaboration with Fusion, features nine strategically placed signature series speakers and a subwoofer, delivering superior sound quality with minimal distortion. Safety is enhanced by a First Mate marine safety and security system that replaces the traditional kill switch lanyard with a wearable FOB that automatically shuts off the engine if the operator moves beyond a preset distance.

Additional Exterior Amenities

The SLX 280 includes an electrically actuated power tower that provides 6 feet, 7 inches of headroom when raised and 4 feet, 11 inches when lowered. This tower features a downlight projecting the Sea Ray logo, a slide-out shade for cockpit sun protection, and options for additional tower speakers and swiveling wakeboard racks. The cockpit is illuminated by an optional lighting bundle with RGB LED lights both above and below the waterline, docking lights, and an illuminated Sea Ray badge. Boarding is facilitated by a solid wood step on the starboard side and a swinging transom gate to port. The integrated swim platform includes a concealed four-step stainless steel ladder with grab handles. The large sun pad, measuring 68 by 42 inches, offers another social area with cup holders and under-pad storage that can double as a cooler.

Bow Area and Storage

Accessed through a hinged windshield with a locking air dam, the bow area features two forward-facing loungers and a rear-facing bench, all equipped with fold-down armrests and multiple cup holders. The seating is spacious, extending 58 inches from the backrest forward, accommodating taller guests comfortably. Underneath the bow lounges are storage compartments, with the starboard side offering a larger space. Dedicated storage spots are provided for the bow filler cushion and tables included in the comfort bundle. Optional equipment includes a bow boarding ladder and an anchor bundle featuring an electric windlass and washdown nozzle.

Conclusion

The Sea Ray SLX 280 Outboard is a thoughtfully designed vessel that balances upscale amenities with powerful propulsion and innovative features. Its spacious and ergonomically refined cockpit, advanced helm technology, and versatile exterior options make it well-suited for boaters seeking luxury, performance, and customization. The model’s attention to detail and functional design elements support a comfortable and enjoyable boating experience, whether for social gatherings or adventurous outings.
