Sea Ray SLX 350 OB: BoatTEST Review

Reviewed by Jeff Hammond

Boat Test Review on BoatTest.com

Overview

The Sea Ray SLX 350 OB is a luxury bow rider designed with ample space for entertaining, enhanced by its outboard power configuration. This model leverages the additional room afforded by outboard engines to maximize comfort and functionality throughout the boat.

Exterior Design and Swim Platform

At the stern, the swim platform features twin sections that extend three feet eight inches to either side, providing generous space for water access. The deck is T-covered for durability and aesthetics. Powering the boat are triple 300 horsepower Mercury Verado outboard engines, neatly installed within the motor well. On the port side, a flip-out swim re-boarding step facilitates easy water entry, complemented by a convenient handhold cutout. Underwater lighting enhances the vessel's visual appeal during low-light conditions.

Cockpit and Seating Areas

Moving forward, a hatch lifts to reveal a wide seat upholstered with premium materials consistent with the SLX luxury line. These seats convert effortlessly into separate chaise lounges, accompanied by speakers, beverage holders, and grab rails on both sides. An extendable Sure Shade awning overhead offers welcome protection from the sun. Beneath the seating, an electrically actuated lift opens to expose a large, compartmentalized storage area, illustrating the efficient use of available space.

Cockpit Layout and Amenities

Entry to the cockpit is via an angled walkthrough on the starboard side, which optimizes functional space. The cockpit features opposing seating arrangements, including an L-shaped seat on the port side that wraps around a triangular T-covered pedestal table crafted from teak. Upholstery throughout is upscale, showcasing multiple tones, bead welting, diamond stitching, and plush cushions. Storage compartments are integrated beneath the seats, with additional storage accessible via a helm switch that takes advantage of the outboard engine configuration. Courtesy lighting throughout the cockpit enhances ambiance and safety.

Entertainment and Galley Features

Opposite the L-shaped seating is additional seating with a carry-on cooler stored underneath. The starboard side houses an entertainment center equipped with an electric grill, a covered single-basin stainless steel sink, and covered storage. Below the counter, a stainless steel grab rail, a pull-out trash container, and a cockpit refrigerator are incorporated. High-quality materials such as cored countertops, metal trim, and leather-wrapped stainless steel grab rails underscore the vessel's premium finish.

Additional Seating and Hardtop

Forward on the port side is a double-wide seat featuring premium upholstery and individual flip-up bolsters. The fully upholstered sides include padded armrests and leather-wrapped grab handles, complemented by integrated speakers and stainless steel drink holders. Above this area, a standard hardtop with a central opening sunroof measuring 40 inches by 5 feet 5 inches provides shelter and natural light.

Console and Head Compartment

The console is stylishly designed with covered storage and a recessed beverage holder integrated into a stainless steel rail. Below is a wraparound padded bolster for comfort. Inside the console, a spacious head compartment includes a standard vacuum flush toilet, a solid surface countertop with a stainless steel sink, and a separate pull-out sprayer adjacent to the faucet. A wood shelf is positioned above a tinted window with an opening port light, while a skylight overhead adds natural illumination.

Cabin and Bow Area

A 23-inch-wide walkthrough to the bow features a door on the starboard side that, when opened, reveals a step leading into a modest cabin. This cabin includes a television and offers minimal sleeping space or additional storage options. The walkthrough can be closed off to maintain warmth during cooler conditions, with interconnected window latches enhancing security. The bow itself provides spacious seating with dual loungers equipped with flip-down armrests. Both seats allow occupants to stretch out comfortably, with footrests on the deck. Under the gunwales, speakers, grab handles, beverage holders, and padded bolsters contribute to comfort and convenience. A step leading to the deck facilitates boarding or disembarking from the bow, and storage is available beneath the seats.

Conclusion

The Sea Ray SLX 350 OB combines the luxury and upscale finishes of the SLX lineup with the spaciousness afforded by outboard power. Its thoughtful design maximizes the full length of the boat for entertaining, offering a compelling blend of style, comfort, and functionality. This thorough inspection highlights the vessel's strengths in layout, materials, and amenities, making it a notable choice in the luxury bow rider category.
