2005 Cobalt 343

Cobalt Boats of Neodesha, Kansas has built its reputation as one of North America's premier builders of luxury sport boats, prized for hand laid fiberglass construction, sharp deep V hulls, premium upholstery, and a level of fit and finish that few production builders match. The 343 sits at the very top of the Cobalt range as the flagship performance cruiser, pairing genuine offshore capability with the comfort and craftsmanship the brand is known for. The Cobalt 343 is a high performance express cruiser that combines a large, beautifully appointed open cockpit with an enclosed cabin and head below. This example is powered by twin MerCruiser 496 MAG HO 425 horsepower gas engines on stern drives with through prop exhaust, delivering effortless cruising and exhilarating top end performance. The cockpit features wraparound Ultraleather seating, a full instrumentation helm, a refreshment centre, and an extended swim platform, while the cabin below sleeps two and includes an enclosed head. This particular 343 has been meticulously maintained and always stored indoors in a heated garage, and it shows throughout. The hull received new bottom paint in 2025 and a fresh original style Cobalt black stripe, and the boat has just been through a complete 2026 service that includes engine oil changes, new belts, drive oil, two new batteries, and all necessary fluids. New 24 pitch propellers and new anodes are part of the 2026 freshening as well. Included with the boat is a custom fit heavy duty triple axle galvanized bunk trailer fitted with brand new disc brakes and four new tires, making transport, launching, and winter storage effortless. With only 289 hours on the engines, indoor storage its entire life, and a trailer included, this is a rare opportunity to step into a turn key flagship Cobalt.
