Technical Specifications

The SLX 310 demands everyone’s full attention. And by everyonewe mean not only the abundance of people who can lounge comfortably onboard, but also the passersby whose heads will turn at the iconic styling and elegant hull sculpting. An expansive cockpit social area, an aft-facing lounger that converts to a sunpad, and a standard wetbar make relaxation and onboard entertaining a given. Underway, the delight of good company merges with the thrill of precision performance, as the SLX’s available twin MerCruiser engines and innovative Quiet Ride™ hull featuring Tuned Transom® combine forces beautifully.


The science behind the silence

Quiet Ride™, featuring Tuned Transom®, is a system of technological advances exclusively available on Sea Ray boats. It reduces Noise, Vibration and Harshness (NVH) by up to 50%, so conversations are easier, fatigue is reduced, concentration is enhanced. The natural world feels more natural, more intimate, and you experience the wonder that drew you to boating in the first place.

Reduction in NVH as much as 50% with Quiet Ride

Decibel Comparison at full cruising speed:
Baseline Boat Average 86.2: As loud as a freight train from 15 meters away. Quiet Ride Average: 79.4*: A normal passenger car at 65 mph.
*A 10 decibel increase means sound is twice as loud.


Precise just became more precise

Mercury’s SmartCraft Digital Throttle & Shift (DTS) system delivers effortless command of your engines. Dual controls* with inset switches put control at your fingertips, literally. Enjoy smoother shifting, easier docking, more immediate throttle response and cutting-edge information displays. Performance is more predictable and responsive than ever before.

Digital Throttle


Know it all

Experience confidence and effortless control at your fingertips. High-tech and hands-on, the SLX’s Dynamic Display provides seamless vessel data, lighting control and navigation capabilities from a dual 12″ and 7″ touchscreen electronics display. Set your cruises to music, too, with an integrated stereo, wireless Bluetooth, dual zone volume control, amplifier and six weatherproof speakers.

The joy of driving

The Axius® joystick propulsion system puts control of the SLX 310 in the palm of your hand. Tight fairways and docks are a breeze, with easy movement in any direction, spinning in place, and Skyhook for effortless station-keeping. So simple a child can do it. Simple for adults, too.

Axius Propulsion

The wake you make

Dynamic Running Surface™ automatically optimizes running attitude and trim, delivering incredible stability and performance. Large, triangular planes in the hull create an articulated running surface that improves acceleration, reduces bow rise and keeps the boat at optimal trim, no matter the load. DRS also allows skiers and wakeboarders to define presets–letting you shape the perfect wake height.

Dynamic Running Surface

Active Trim

Active Trim by Mercury Marine is now available on all SLX models. Designed to suit entry-level and expert boaters alike, Active Trim simplifies boat operation while improving engine performance and decreasing fuel costs. New boaters are immediately able to properly trim boat engines with no intimidating learning curve, and experienced boaters can get the benefit of perfect trimming without constantly monitoring and adjusting trim with changes to boat speed or when going into turns.

Active Trim

No sweat

Enjoy protection from the sun and elements with the SLX 310’s standard electric tower with articulating bimini system. An available power arch makes raising and lowering the tower a breeze. An optional fiberglass hardtop with electric Sureshade takes coverage to the next level.
