Sea Ray SLX 350: BoatTEST Review

Reviewed by Jeff Hammond

Overview

The Sea Ray SLX 350 represents the latest evolution in Sea Ray's sport luxury lineup, building upon the foundation of the previous 350 model with numerous enhancements. This model focuses on improved functionality, comfort, and performance, responding directly to customer feedback to create a premium dayboat designed for extended social outings on the water.

Exterior Design and Deck Features

Starting at the stern, the SLX 350 features a 38-inch deep sea deck with four tie-down brackets for securing large water toys without deflating them. The previous undermount swim step has been replaced by an 18-inch deep submersible center section, allowing multiple people to enjoy a private beach-like experience simultaneously. The swim platform includes an undermount reboarding ladder with grab handle to meet NMMA and ABYC standards. The cockpit is accessed via an 18-inch angled walkway elevated 10 inches, designed to minimize obstruction to seating. Seating wraps around the aft, port, and forward starboard sides, creating a comfortable social atmosphere enhanced by upgraded upholstery, beverage holders, USB ports, and a Fusion stereo remote. The cockpit table folds to reveal a curved grab handle, and a 36-quart carry-on cooler is integrated beneath the forward corner seat. The refreshment center on the starboard side includes a Corian countertop, sink, electric grill, refrigerator, and trash receptacle. The bow seating area accommodates 18 people with face-to-face arrangements, twin solid wood tables convertible to a full-length lounge with filler cushions for sunbathing. Additional features include flip-down armrests, dedicated cooler storage, a concealed windlass and roadlocker, washdown, remote spotlight, and four 10-inch cleats. Shade is provided by a well-supported hardtop with carbon fiber styling, a manually operated sunroof, an extendable shore shade awning, and an optional bow shade supported by carbon fiber stanchions.

Interior Living Spaces

The interior layout has been reconfigured with the head and berth compartments swapped to provide more spacious accommodations. The port-side hideaway cabin offers four feet seven inches of headroom and three feet seven inches seated headroom, featuring a comfortable couch facing a 19-inch TV mounted on the starboard bulkhead. Storage includes lockable glove compartments, USB ports, and a 110-volt outlet powered by shore power. The cabin benefits from natural light through a skylight, hull side window, and an opening port light, supplemented by air conditioning powered via an inverter, eliminating the need for a generator. The convertible couch allows the space to function as a berth. The head compartment, accessed via a console side door, is fully fiberglass lined and includes a vacuum flush head, hull side window, opening port, powered vent, fiberglass vanity with molded sink, and non-skid deck treatment.

Helm and Operational Features

The helm station reflects the upscale nature of the vessel with a standard glass dash featuring dual Simrad multifunction displays available in nine or 12-inch sizes. These displays integrate chart plotting, echo sounding, full vessel electrical switching, and comprehensive Mercury engine and control interfaces, including troll mode, active trim, dynamic running surface, bow hook, sky hook, drift hook, and programmable towing profiles. The helm also includes spotlight control, an upgraded Fusion Apollo series stereo with Wi-Fi and Sirius XM capabilities, push-button electrical switches, a tilt-mounted steering wheel, trim tab controls, a full-length cubby, Mercury digital throttle and shift, and an Axius joystick piloting system for effortless docking. The engine compartment hatch is electrically actuated for convenience.

Power and Performance

The SLX 350 offers power options starting with twin 300 horsepower 6.2-liter engines, up to twin 350 horsepower 8.2-liter Mercruiser Mag engines equipped with C-Core and Axius joystick controls. The boat incorporates Quiet Ride technology with enhanced soundproofing and a tuned transom to reduce noise. Measuring 34 feet 6 inches overall with a 10-foot 6-inch beam and a 39-inch draft, the vessel weighs approximately 13,890 pounds empty. During testing with full fuel and three passengers (estimated 15,557 pounds), the twin 380 horsepower 8.2-liter Mag engines with Bravo 3 outdrives and 28-pitch propellers reached a top speed of 50.8 miles per hour at 4,800 rpm. The best cruise speed was 28.7 miles per hour at 3,000 rpm with a fuel burn of 25 gallons per hour, yielding a range of 183 statute miles. In calm conditions, cruising speed could be increased to 36.1 miles per hour at 3,500 rpm while maintaining the same fuel efficiency. The boat planes in 6.1 seconds, accelerates to 20 miles per hour in 9.1 seconds, and reaches 30 miles per hour in 15.1 seconds. Handling is solid and confident, with a 22-degree roll into hard turns and smooth performance in one-foot chop without pounding or haul slap.

Conclusion

Sea Ray has significantly refined the SLX 350 from the keel up, enhancing nearly every aspect of the boat to meet the demands of discerning customers. The result is a premium dayboat that combines upscale design, thoughtful functionality, and strong performance, ideal for social outings with friends and extended time on the water. The SLX 350 stands out as a versatile and well-appointed vessel in its class.
