2023 Sea Ray SLX 310 Outboard: Premium Dual-Console Cruiser with Mercury Verado Power
Overview
The 2023 Sea Ray SLX 310 Outboard represents a thoughtfully engineered dual-console cruiser designed for buyers seeking a balance of open-water capability, comfortable day cruising, and accessible performance. At 31.5 feet in length with a 10.25-foot beam, this outboard-powered model delivers the shallow-draft responsiveness and fuel efficiency characteristic of modern mercury outboard propulsion while maintaining the interior comfort and helm sophistication expected from Sea Ray's heritage in recreational boating. Powered by twin 300-horsepower JPO Black Mercury Verado outboards, the SLX 310 produces a combined 600 horsepower—a configuration that supports a maximum speed of 34.76 knots and a cruising speed of 26.07 knots. This power-to-weight ratio enables confident acceleration and efficient cruising across a wide range of water conditions, while the outboard configuration preserves interior volume and eliminates the mechanical footprint of inboard engines, a significant design advantage for a vessel in this size and category. Located in Brick, New Jersey, this 2023 model carries the factory specifications and build quality associated with Sea Ray's current production standards, making it an appealing option for buyers in the Northeast and Mid-Atlantic regions seeking a late-model, ready-to-operate cruiser.
Design and Hull Characteristics
The SLX 310 is built on Sea Ray's proven center-console-inspired dual-console platform, a layout that maximizes usable deck space while providing an elevated helm station with excellent sightlines and weather protection. The dynamic running surface—a stepped hull design that improves planing efficiency and reduces drag—contributes to the vessel's responsiveness at cruising and wide-open throttle speeds. The 3.17-foot draft is a practical advantage for navigating coastal shallows, inlets, and river systems without the draft penalty of inboard propulsion. The black hull color paired with the black and horizon stripe scheme presents a contemporary, purposeful aesthetic that appeals to buyers favoring understated elegance over high-visibility graphics. The 10.25-foot beam provides stable platform behavior in beam seas while remaining within the practical limits for trailering, a consideration for owners who value seasonal storage flexibility.
Helm Station and Electronics
The SLX 310's helm arrangement centers on a Simrad Select Response 12-inch multifunction display—a capable, user-friendly marine electronics platform that integrates navigation, sonar, autopilot capability, and vessel monitoring functions. The Simrad ecosystem is known for intuitive menu structures and strong integration with modern marine networks, making it accessible to both experienced operators and new boat owners. The dual-console layout positions the primary helm to starboard with full helm seating, engine controls, and instrument visibility. The elevated vantage point delivers commanding sightlines across the bow and beam, essential for safe maneuvering in crowded anchorages and coastal traffic. The dune-colored cockpit upholstery—a practical choice that resists fading and heat absorption—complements the overall design while maintaining comfort in extended sun exposure. Navigation and communication equipment includes a VHF radio with antenna, supporting both hailing and distress communications. Docking lights and a spot light enhance visibility during low-light maneuvering and night operation. An onboard battery charger ensures the vessel's auxiliary electrical systems remain charged during layups and between outings.
Cockpit and Deck Design
The cockpit is configured as a comfortable, multi-functional entertainment and operating space. The infinity woven vinyl flooring—a durable, non-skid synthetic material—resists marine staining, UV degradation, and provides secure footing in wet conditions. Seadek protective matting on the swim platform offers additional grip and thermal comfort for swimmers and water toy operators. An extended sunshade for the hardtop provides overhead weather protection during anchored entertaining and daytime cruising, while a cockpit cover with tonneau configuration protects the entire helm and seating area during storage and transit. A side entry step facilitates boarding from the water or dock, improving accessibility and safety for passengers of varying mobility. Practical amenities include a fiberglass bow side table—a useful surface for drinks, snacks, or small electronics—and an air compressor for water toys, supporting tow sports and recreational water activities. RGBW LED lighting throughout the cockpit and through-hull lights create ambient entertainment lighting during evening anchoring while supporting operational lighting for night navigation. A 12-volt refrigerator mounted in the cockpit provides cold storage for beverages and light provisions without requiring full galley infrastructure, a practical feature for day cruises and overnight anchorings. A flag pole and base with US flag mounting rounds out the deck hardware.
Propulsion and Fuel Capacity
The twin Mercury Verado 300-horsepower outboards represent a modern, electronically controlled propulsion solution engineered for reliability, fuel efficiency, and low-emission operation. The JPO Black designation indicates the premium black-finish variant of Mercury's flagship recreational outboard line, combining high-performance capability with a distinctive aesthetic finish. With a combined 600 horsepower, the SLX 310 achieves its 34.76-knot maximum speed while maintaining efficient cruising performance at 26.07 knots—a speed profile suitable for day cruises, coastal transits, and relaxed exploration of protected waters. The 130-gallon fuel capacity supports extended cruising range at displacement speeds and reasonable transit distances at planing speeds, though specific range calculations depend on actual fuel consumption patterns across the speed envelope. The outboard configuration offers significant advantages over traditional inboard propulsion: reduced weight, lower center of gravity, improved interior volume utilization, simplified maintenance access, and the ability to tilt engines for shallow-water operation and beaching. For owners in the Northeast with access to shallow inlets and coastal bars, this capability is operationally valuable.
Interior Comfort and Accommodations
While the SLX 310 prioritizes open-water day cruising and entertaining, the cabin provides basic overnight capability with a convertible berth arrangement typical of dual-console cruisers in this size range. The interior layout emphasizes efficient use of available space, with adequate headroom and natural ventilation through cabin windows and deck hatches. The brown flooring color scheme creates a warm, inviting interior aesthetic that contrasts with the exterior black and gray tones. Cabin appointments support comfortable short-cruise operation, with sleeping arrangements for two to three occupants and basic galley and head facilities enabling self-sufficient operation away from shore services.
