2026 Sea Ray SLX 400

The 2026 Sea Ray SLX 400 is a 40-foot fiberglass sports cruiser powered by twin Mercury MerCruiser 8.2L MAG ECT engines with Bravo Three X sterndrives, delivering 860 horsepower. The boat reaches speeds up to 43 knots and cruises at 30 knots. It carries 250 gallons of fuel and 50 gallons of fresh water, with a 28-gallon holding tank.

The layout balances entertaining and overnight capability. The expansive cockpit features premium seating around a wet bar, and the bow includes convertible seating with a sunpad arrangement. A fold-down swim terrace extends the swim platform, creating additional water access and lounging space. Below deck, the cabin sleeps four with a queen-sized aft berth and a forward bunk that converts to a social area.

The helm features a modern digital dash with advanced instrumentation and ergonomic controls optimized for comfortable cruising. With a draft of 44 inches at the sterndrives down and 33 inches with them up, the boat is well-suited for varied waters. The SLX 400 combines performance with a social-cruiser design suitable for weekend trips and extended stays.
