Sea Ray SLX 350 Boats For Sale

The Sea Ray SLX 350 is one of the largest bowriders in its class, built around carrying and entertaining a crowd on big water. It carries yacht certification for 18 people total, with seating for 11 facing forward while underway. Shoppers will find the Sea Ray 350 SLX offered in two power formats: a sterndrive model with a hull length overall of 34 feet 6 inches, and the SLX 350 OB outboard version that stretches to 36 feet 11 inches. Both share a 10-foot-6-inch beam. The sterndrive draws 37 inches, while the outboard draws 39 inches.

Engine choices separate the two. The sterndrive SLX 350 runs twin Mercury MerCruiser 350 MAG engines at 300 horsepower as standard, with an upgrade to 380-horsepower 8.2-liter MerCruisers, both turning Bravo Three drives. With the 380-horsepower pair, the boat reaches a top speed just under 50 mph and cruises best between 25 and 30 mph. A test of the standard 300-horsepower sterndrive returned 47.2 mph flat out at 50.2 gph, with a best cruise of 27.8 mph burning a combined 19.5 gph for roughly 205 miles and 7.5 hours of range on a 10% reserve. Planing came in 2.9 seconds, 20 mph in 4.4 seconds, and 30 mph in 6.2 seconds.

The Sea Ray SLX 350 OB swaps in triple 300-horsepower Mercury Verado outboards, which clears the old engine bay and opens cockpit floor space. That setup hit a top speed of just under 60 mph at 6100 RPM, with one run measured at 61.8 mph, and reached 30 mph in under 8 seconds. Best economical cruise sat at 3500 RPM and 31.1 mph, where a 24.2 gph burn produced 1.3 mpg and a 185-mile range with a 10% fuel reserve. Empty weight runs 10,335 pounds. Sea Ray's Dynamic Running Surface trims the planes to hold a near-level cruise attitude, and the hull tracked through mild chop with no hull slap or prop ventilation.

The helm carries a double-wide bolster seat with individual flip-up bolsters. Depending on build, the dash mounts twin Raymarine touchscreens with Mercury VesselView, or twin Simrad screens with Naviop that put lights, bilge pumps and ship's functions on touch control. Either way the boat runs digital throttle and shift, an Axius joystick for docking, and Mercury Skyhook for holding position without an anchor. Quiet Ride technology lines the engine compartment with sound-absorbing material and full-beam bulkheads to keep noise out of the passenger area. Audio comes from a Fusion or Rockford Fosgate system, with Lenco or dynamic trim tabs underway.

The cockpit is set up for entertaining, with wraparound L-shaped seating, swiveling passenger and aft-facing rumble seats, and premium diamond-pattern upholstery with bead welting. A starboard wet bar holds a stainless sink, optional electric grill, refrigerator and a full-size cooler under the seat. A standard fiberglass hardtop with a sliding roof pairs with an electrically retractable sunshade covering the whole cockpit. At the stern, a hydraulically actuated submersible swim platform drops well below the surface, available with inlaid teak, and a flip-up sun lounger lifts to reveal a large storage locker. The bow seats run 4 feet wide and convert to a sun pad with optional teak tables.

Despite the open bowrider format, the SLX 350 includes a real head compartment behind a swinging door to port, plus a day cabin built into the helm console with 54 inches of headroom narrowing to 20 inches, opening port lights, a skylight, and options for air conditioning and a TV for overnighting or a nap. Buyers weighing a Sea Ray SLX 350 for sale should match the propulsion to their use, since the triple-outboard SLX 350 OB delivers notably higher top speed and longer range than the sterndrive, while both used and current listings carry the same entertainment-first layout.
