Overview
2021 Sea Ray SLX 310
The 2021 Sea Ray SLX 310 is a premium express bowrider built for performance, comfort, and all-day entertaining on the water. Powered by twin MerCruiser ECT 4.5L MPI Axius Bravo III sterndrives, it delivers confident acceleration, precise handling, and smooth cruising in a wide range of conditions. At the helm, the dual digital dash system and integrated GPS-based Active Trim keep control intuitive and responsive, while QuietRide technology helps reduce vibration and noise for a more refined ride. A powerful combination of docking lights, stainless navigation lighting, LED courtesy lighting, blue LED accents, and blue underwater thru-hull lights gives the boat a striking presence from day to night.
Designed with entertainment in mind, the SLX 310 features a fiberglass hardtop with integrated lighting, plus an extended sunshade, along with a power water sports tower with an articulating electric bimini for versatility on the water. The cockpit is finished in stone upholstery with grey flooring, complemented by SeaDek on the swim platform and snap-in SeaDek throughout the cockpit and bow for comfort and traction. A fiberglass wet bar with sink and faucet, 12V refrigerator option, solid surface lid with stainless grab handle, and thoughtfully placed beverage holders make onboard hosting effortless. Storage is abundant with a lockable glove box, ski/wakeboard storage with gas-assisted lid, cooler storage, and a hidden trash receptacle, while the cockpit table options add flexibility for dining or lounging. Around the water near MarineMax Excelsior, this SLX 310 fits perfectly into life on Lake Minnetonka—whether cruising past Excelsior Bay, anchoring near Big Island, or pulling into shore after a sunset run along the shoreline homes of Wayzata and Deephaven.
