Sea Ray SLX 400: BoatTEST Review
Overview
The Sea Ray 400 SLX with outboard power represents a refined blend of performance and comfort, featuring the latest Mercury 300 horsepower V8 outboards. This model maintains ample swim platform space despite the outboard configuration and integrates advanced technology and thoughtful design elements throughout the vessel.
Exterior Design and Swim Platform
The swim platform remains spacious, extending only 16 inches from the transom at its narrowest point, ensuring no compromise in usable space despite the outboard engines. The transom is equipped with 9-inch pull-up cleats on both sides, and deep storage compartments under the port side seating accommodate longboards, skis, and wakeboards. A convenient inflator for water toys is included, along with a cleverly stored pole that can be used to support a stand-up transom shower. Shore power connections, city water inlet, electrical and TV hookups, and a fresh water washdown are all neatly organized in one area, complemented by USB connectivity adjacent to the lounge.
Power and Performance
Powered by triple Mercury 300 horsepower V8 outboards featuring advanced technology such as larger alternators and quieter operation, the 400 SLX delivers impressive performance. The boat weighs approximately 21,258 pounds with fuel and passengers aboard. During testing, it reached a top speed of 51.8 miles per hour at 5,900 RPM, with an optimal cruise speed of 32.9 miles per hour at 4,000 RPM. Fuel consumption at cruise was measured at 34.8 gallons per hour, yielding a range of 319 statute miles while retaining a 10% fuel reserve. The vessel planes quickly, achieving 20 miles per hour in 6 seconds and 30 miles per hour in 9.5 seconds. Handling is responsive with a comfortable turning radius, and the joystick docking system allows for precise maneuvering in tight spaces. The hull design provides a smooth ride with minimal hull slap or pounding, even when crossing wakes at speed.
Mechanical and Systems Layout
The engine compartment is thoughtfully arranged, featuring an optional SeaKeeper 3 gyro stabilizer mounted centrally with stringers pre-built to accommodate it. On the port side are house and engine start batteries along with the generator, while the starboard side houses hydraulic components for the terrace. The vessel includes a generator and the innovative Fathom ePower system, which provides 22 kilowatt-hours of lithium-ion battery capacity to power onboard electrical systems such as air conditioning, electric grills, and refrigeration. This system intelligently manages power loads and interfaces with the Simrad multifunction displays for real-time monitoring and can be recharged via engine alternators, generator, or shore power.
Helm and Electronics
The helm station is one of the most refined in its class, featuring a soft-touch dash and dual 12-inch Simrad Evo 3S multifunction displays with the NaviOp system for comprehensive control of electrical systems and lighting presets. The displays support up to six panels simultaneously and include tide graphs, engine data, vessel controls such as cruise control, troll control, and active trim. Additional helm features include sport exhaust controls, flush-mounted Fusion stereo, spotlight control, Seakeeper controls, auto glide automatic trim tabs, joystick docking, and a Simrad VHF radio. Dual helm seats are ergonomically designed with 24-inch width, flip-up bolsters, and adjustable fore and aft swivel functionality. Generator and 120-volt AC controls are conveniently located beneath the port helm seat.
Deck and Bow Features
The deck layout includes strategically placed cleats for secure mooring, with a 10-inch cleat forward of midships and another at the bow. The bow area features dual hatches providing access to the ground tackle, which can be remotely controlled. Fresh water washdown is located nearby, flanked by LED navigation lights and a remote-controlled spotlight on the port side, enhancing safety and convenience.
