Our Thoughts

This 2023 Sea Ray SLX 400 represents a rare ownership opportunity—a single-owner, freshwater-kept entertainer that has been meticulously maintained since delivery at the Lake of the Ozarks. With only 55 hours on twin 8.2L Mercury engines and 85 hours on the Kohler generator, this 40-foot center console has been pampered under a covered dock with full protective cover, serviced exclusively by the local Sea Ray dealer, and kept on a lift to preserve its condition.

The SLX 400 earned its NMMA Innovation Award for a reason. Sea Ray engineered this platform as a genuine social hub—what they call "The Entertainer"—where peak performance, superior comfort, and state-of-the-art technology converge. The 12.08-foot beam and thoughtful interior architecture create an inviting environment that works equally well for cruising, entertaining, or day-boating on inland waters. The fold-down, power-actuated swim platform with integral terrace extends the social space aft, while the expansive bow seating and opposing cockpit social area ensure every guest feels at home.

Power & Propulsion
Twin 8.2L Mercury engines deliver the performance Sea Ray designed into this hull, supported by Quiet Ride™ Technology with proprietary tuned transom engineering by Omni Products that reduces vibration and noise. The 250-gallon fuel capacity supports extended cruising, while the 50-gallon fresh-water capacity and integrated windlass system with rope/chain and galvanized anchor add practical cruising capability.

Technology & Navigation
Twin Simrad displays with integrated radar provide modern, intuitive helm control. The digital helm interface is clean and purposeful—a far cry from the cluttered dashboards of earlier designs. Navigation lights are stainless steel with motorized mast light, and the curved, tempered windshield with tinted glass and black matte frame provides excellent visibility and protection.

Entertaining & Hospitality Features
This boat was optioned for entertaining. Dual BBQ grills, two cockpit refrigerators with pull-out drawers, and a cabin refrigerator support extended gatherings. The wet bar features a solid-surface countertop, stainless steel sink with faucet, and dedicated trash receptacles. Twenty-nine LED-lit beverage holders with stainless steel and rubber inserts are distributed throughout the cockpit, and a teak cocktail table anchors the social area. The hardtop with enclosed ceiling and courtesy lighting provides weather protection and ambiance.

Cabin Comfort
The light gray interior with black exterior and blue boot stripe creates a modern, clean aesthetic. Cabin air conditioning ensures comfort in warm climates, while the sliding, lockable cabin entry and bow walk-through with stainless steel supports facilitate easy movement. Acrylic skylight in the dash provides natural light, and courtesy lighting throughout supports evening entertaining.

Storage & Functionality
Storage is thoughtfully integrated: forward deck hatch, side panel tubs in the bow, below-deck seat storage port and starboard, bumper floor storage, shoe storage aft, and dedicated storage below the ETS aft seat. The cockpit cooler with dedicated storage, fiberglass floor liner with direct overboard drainage, and multiple 120V GFI and 12V accessory outlets (3) support practical boating needs.

Seating & Social Layout
The seating configuration is purpose-built for entertaining. U-shaped forward bow seating with fixed cushions and arm rests faces the action, while

2023 Sea Ray SLX 400: Premium Entertaining and Performance at Sunrise Beach
Overview
The 2023 Sea Ray SLX 400 represents a refined approach to mid-size luxury cruising and entertaining, combining thoughtful design with proven engineering in a 40-foot platform built for fresh water boating. Held on a lift and under cover since its delivery, this single-owner SLX 400 has accumulated only 55 hours on its twin Mercury 8.2 engines and 85 hours on its Kohler generator, reflecting meticulous ownership and minimal use. Located in Sunrise Beach, Missouri, this vessel exemplifies the care and attention that define a properly maintained late-model sportcruiser, backed by a transferable $12,000 Brunswick Premier Warranty extending through July 2029. The SLX 400 earned recognition as an NMMA Innovation Award winner, a distinction that reflects Sea Ray's commitment to blending performance, comfort, and technology within a category-leading package. The model's tagline—"The Entertainer"—speaks directly to its design philosophy: every element, from the expansive cockpit and cabin layout to the innovative fold-down swim terrace and sleek digital helm, has been engineered to create an inviting social environment that transforms boating into premium hospitality on the water.
Design and Hull Construction
The SLX 400 is built on a fiberglass hull incorporating Sea Ray's Quiet Ride™ technology and proprietary Tuned Transom® system developed with Omni Products. This engineering reduces vibration and impact, a particularly valuable feature for longer cruises and rough-water conditions on inland lakes and coastal waters. The hull employs high-performance vinylester resin and a fiberglass stringer system with forward interior liner reinforcement, contributing to structural rigidity and longevity. The deck is comprehensively finished with stainless steel hardware throughout: six 10-inch thru-bolted cleats, two 8-inch pop-up cleats, bow eye with scuff plate, and stern eyes provide secure tie-off points. The rub rail combines PVC construction with stainless steel inserts for durability and refined aesthetics. Forward deck storage with a hatch provides practical stowage, while the integral windlass with rope and chain capability—complete with galvanized anchor and bow wash-down controls—supports confident anchoring and maneuvering in tight quarters. The signature fold-down swim platform, actuated via power controls on the starboard side, extends the usable waterline and creates an inviting entry point for swimmers and water sports enthusiasts. This integrated terrace design is a hallmark of the SLX series and distinguishes the boat from conventional transom layouts.
Cockpit Design and Entertaining Layout
The cockpit is where the SLX 400's "entertainer" identity becomes most apparent. The space is organized around a social seating arrangement featuring opposing seat groups: large U-shaped forward bow seating with fixed cushions and arm rests faces inboard toward a cockpit social area, while the transom Sungate seating with integrated drink holders creates a secondary gathering zone. This opposing layout naturally encourages conversation and engagement, a deliberate choice that sets the boat apart from single-orientation fishing or performance-focused designs. The dual bucket helm seats feature slider mechanisms, flip-up thigh-rise bolsters, and floor footrests, allowing the captain and companion to adjust for comfort during extended running. The companion seat offers 180-degree swivel capability with paddle adjustment levers, enabling the co-pilot to face either forward or aft depending on the activity. Storage is distributed thoughtfully throughout the cockpit: side panel tubs in the bow, dedicated bumper and shoe storage, below-seat compartments, and an aft seat storage area ensure that entertaining essentials—towels, sunscreen, beverages—remain organized and accessible. The teak cockpit table anchors the social area, while a wet bar on the starboard side includes a refrigerator with pull-out drawers, solid-surface countertop, stainless steel sink with faucet, and trash receptacles. Twenty-nine LED-lit beverage holders with rubber inserts are distributed throughout the cockpit, reflecting the boat's emphasis on guest comfort and refreshment. The hardtop is fiberglass construction in Arctic White with an enclosed ceiling and courtesy lighting, providing weather protection without the visual bulk of a full enclosed cabin. Deck entry doors on both port and starboard sides facilitate flow between the cockpit and cabin, while a starboard walk-through transom with door creates a secondary entry point to the swim platform.
Cabin and Interior Accommodations
Below deck, the cabin layout prioritizes comfort and convenience for overnight cruising or extended entertaining. The sliding lockable cabin entry door provides security and climate control, while the acrylic skylight in the dash floods the space with natural light. The cabin is finished in light gray upholstery and trim, creating a bright, airy aesthetic that visually expands the interior volume. Sleeping accommodations include a full cabin berth, though the specific configuration is not detailed in the available specifications. The cabin refrigerator—in addition to the two cockpit refrigerators and wet bar unit—supports provisioning for multi-day trips. Cabin air conditioning, powered by the Kohler generator, maintains comfort in warm weather, essential for fresh water boating in the Midwest and summer cruising conditions. Courtesy lighting throughout the cabin, combined with 120V GFI-protected outlets and 12V accessory outlets, ensures modern convenience. The fiberglass floor liner with direct overboard drainage prevents water accumulation and simplifies cleaning. Stainless steel grab handles with leather-wrapped grips provide safety and a refined tactile finish.
Helm and Electronics
The SLX 400's "sleek digital helm" is anchored by twin Simrad displays, including integrated radar capability. Simrad's marine electronics platform provides comprehensive navigation, fish-finding, and situational awareness, with radar enabling confident operation in low-visibility conditions and rough water. The dual-display setup allows the captain to configure screens for navigation, sonar, and engine monitoring simultaneously, a professional-grade approach to helm ergonomics. Cockpit USB stereo controls provide convenient audio management, while the acrylic skylight in the dash maintains forward visibility without glare. The tempered, tinted curved windshield with black matte frame offers UV protection and a refined appearance.
Power and Propulsion
Twin Mercury 8.2-liter gasoline engines deliver the SLX 400's performance envelope. With only 55 hours of operation, both engines remain in early-life condition. The 250-gallon fuel capacity supports extended cruising range, while the 50-gallon fresh water capacity serves the cabin, galley, and wash-down systems. The Kohler generator, with 85 hours logged, provides 120V shore power and AC climate control independent of the main engines. This setup enables comfortable anchoring and entertaining without running the main engines, a significant quality-of-life feature for extended stays in protected waters or marinas.
Equipment and Upgrades
This SLX 400 is equipped with a comprehensive package of premium options, reflecting the owner's commitment to maximizing the boat's entertaining and cruising potential:
  • Twin BBQ Grills: Dual cooking stations enable hosting larger groups and meal preparation without galley limitations.
  • Twin Cockpit Refrigerators: Redundant cooling capacity ensures beverage and food preservation throughout entertaining events.
  • Cabin Refrigerator: Supporting overnight provisioning and extended cruising.
  • Retractable Sunshade: Motorized sun protection over the cockpit social area, extending comfortable outdoor time in bright conditions.
  • Cabin Air Conditioning: Climate control powered by the Kohler generator, essential for Midwest summer boating.
  • Twin Simrad Displays with Radar: Professional-grade navigation and situational awareness.
  • Kohler Generator: Providing independent AC power for air conditioning, refrigeration, and shore-power conveniences.
The exterior finish combines a light gray hull with black exterior and blue boot stripe, a contemporary color scheme that balances visibility with refined aesthetics.
Condition and Maintenance
This vessel's provenance strengthens its appeal to discerning buyers. Sold new at the Lake of the Ozarks and retained by a single owner, it has been consistently serviced by the local Sea Ray dealer. Storage on a lift under a covered roof dock and full protective cover has minimized exposure to weather and UV degradation. The fresh water environment of the lake system reduces salt-related corrosion compared to coastal boating, extending the life of stainless steel hardware, engine components, and electronics. The Kohler generator and Mercury engines, combined with minimal operating hours, represent significant deferred maintenance value. The transferable $12,000 Brunswick Premier Warranty through July 2029 provides additional assurance and support for the new owner.
