2026 Cobalt R4 OB

The 2026 Cobalt R4 OB is a 24-foot fiberglass bowrider powered by a single 300-horsepower Yamaha F300XSB2 outboard engine. Built with Cobalt's attention to detail, the boat features a contemporary design accented by a graphite gray stripe and finished in a clean, modern aesthetic suitable for both leisure cruising and water sports.

The R4 OB is equipped with a white folding arch and ebony bimini top for sun protection, complemented by tonneau covers for the bow and cockpit. An electric adjustable seat allows the driver to customize seating position for comfort and visibility. Boarding and water access are aided by a port-side ladder, while a set of four fender clips with line facilitates docking. A battery maintainer and charger keep the electrical system ready between outings.

The open layout prioritizes social spaces with ample seating throughout the bow and cockpit areas. Storage is integrated into the design to accommodate gear and water toys. The single-engine configuration simplifies maintenance while the Yamaha powerplant delivers responsive handling and fuel efficiency across varying water conditions.
