Sea Ray SLX 310 OB: BoatTEST Review

Reviewed by Jeff Hammond

Overview

The Sea Ray SLX310OB is a luxury bow rider that builds upon the established stern drive version by incorporating outboard power, which allows for increased space utilization. This 31-foot, 6-inch vessel features a beam of 10 feet, 2 inches, and a draft of 32 inches. Designed with upscale appointments and spacious accommodations, the SLX310OB offers a blend of performance, comfort, and premium finishes that justify its reputation within Sea Ray's SLX lineup.

Helm and Controls

The helm of the SLX310OB exemplifies Sea Ray's commitment to quality with a glass dash and an upholstered console. It is equipped with a 12-inch Medallion display positioned ahead of the steering wheel and a 7-inch display to the left, complemented by a 4-inch color SmartCraft display on the lower right. These interfaces provide selectable engine and system information, all controllable via touchscreen or a joystick on the panel. The lower panel includes lighting controls with a graphic boat representation for intuitive operation. To starboard, digital engine controls and a dynamic trim system are situated just ahead of Mercury’s Joystick Piloting for Outboards (JPO), which facilitates precise maneuvering around docks. The helm seat is double-wide with individual flip-up bolsters, enhancing comfort and visibility for the operator.

Performance and Handling

Powered by twin 350 horsepower Mercury Verado outboards with 19-pitch Revolution props, the SLX310OB achieved a top speed of 53.4 miles per hour at 5,900 rpm during testing. Its best economic cruise was recorded at 31.9 miles per hour at 4,000 rpm, consuming 20.1 gallons per hour, which translates to approximately 1.6 miles per gallon and a range of 250 statute miles while maintaining a 10% fuel reserve from its 175-gallon capacity. The boat accelerated to planing speed in 4.7 seconds, with a bow rise of 7 degrees settling to a 5-degree bow-high cruising attitude. Further acceleration milestones included reaching 20 mph in 7.2 seconds and surpassing 30 mph in 10.5 seconds. Handling tests revealed a tight turning radius of 17 degrees with the helm hard over, producing a pronounced wall of water indicative of strong tracking and minimal sliding. The vessel demonstrates minimal chine walking and maintains composure even when encountering wakes, providing a smooth ride. Docking maneuvers were notably effortless using Mercury’s joystick piloting system, which offered immediate response and balanced control between bow and stern.

Exterior Features and Deck Layout

The SLX310OB’s exterior is thoughtfully designed for both utility and luxury. The twin outboard engines are installed to allow full walkthrough access to the swim platform, which extends to each side. A flip-out swim boarding seat on the port side enhances boarding comfort compared to a traditional ladder. Forward of the platform is a spacious lounger measuring 5 feet 4 inches across, convertible into regular seating with five adjustable positions. Premium two-tone upholstery with diamond-pattern stitching accentuates the upscale aesthetic. Underneath the seating areas, there is extensive self-draining storage with compartmentalization and hangers for organization, secured by robust hinges and support struts. The cockpit features a self-draining storage compartment at the entry with a turn-and-lock latch and gasket sealing. To starboard, an engine flush connection and freshwater shower are conveniently located. The walkthrough to the bow is angled to maximize cockpit space and includes a built-in self-draining cooler in the step. Wraparound seating to port with a standard fiberglass pedestal table and opposing seating across the cockpit provide ample social space. The observer seat swivels to join the main seating area, and storage is abundant, including deck compartments and integrated carry-on cooler space. The wet bar to starboard includes an electric grill under a solid-surface lid, a freshwater sink, trash receptacle, and refrigerator, all surrounded by padded bolsters and stainless-steel grab rails.

Interior Amenities and Bow Area

The port console houses a covered storage compartment with a padded recessed area for personal items, secured by a stainless rail with integrated beverage holders. Below, a padded bolster wraps the console, behind which is a porcelain vacuum-flush head, additional storage, and a stainless steel sink recessed into a solid-surface countertop. A hull-side window with an opening port light provides ventilation and natural light. Overhead, a standard hardtop with a manually opening sunroof offers shade, complemented by an electrically actuated SureShade awning that extends further aft. The bow seating area is expansive and comfortable, featuring double-wide forward-facing seats with padded bolsters and flip-down armrests. Recessed aft-facing speakers and stainless grab rails enhance both comfort and safety. A pedestal base accommodates an optional bow table, and storage is accessible beneath the seats, behind the starboard seatback, and under a deck hatch. The forward-most hatch conceals an anchor windlass with a cleat for securing the anchor rode and a remote control positioned to port. Additional features include navigation lights, 8-inch cleats, and an optional freshwater shower, underscoring the vessel’s utility and luxury.

Conclusion

The Sea Ray SLX310OB successfully combines the spaciousness and versatility of a large bow rider with the refined luxury and advanced features characteristic of the SLX lineup. Its twin outboard powertrain delivers strong performance and responsive handling, while the thoughtfully designed helm, cockpit, and bow areas provide comfort and convenience for both operators and guests. With premium materials, abundant storage, and practical amenities, the SLX310OB stands out as a compelling option for those seeking a high-end, performance-oriented bow rider.
