2010 Cobalt 276 - Big Power, Big Fun, Big Water Ready!

This boat was $129,648 new!

Looking for the boat that does it all - luxury, performance, and style that never goes out of fashion? Meet the 2010 Cobalt 276, powered by the legendary MerCruiser 8.2L big block. Fire it up, hit the throttle, and you'll feel why owners say this boat is "as smooth as a sports car on water."

Why people love the Cobalt 276 (reviews & factory brochure highlights):

  • Luxury meets muscle - Cobalt is famous for its fit and finish, and the 276 is a shining example. Deep cushions, rich upholstery, stainless touches, and details everywhere you look.

  • Wave-crushing ride - The 276 isn't just for calm lakes. With its solid build and deep-V hull, it eats up chop and makes rough water fun again.

  • Party-ready layout - Room for the whole crew (and then some). Stretch out in the wraparound seating, crank up the tunes, and let the day disappear.

  • Swim platform heaven - Cobalt's signature extended platform sits just above the waterline-perfect for hanging out, swimming, or gearing up for water sports.

Performance that makes you grin
The 8.2 big block gives you all the torque you'll ever want. Whether you're loading it with friends, tubing, or just cruising, this boat jumps on plane fast and stays smooth at speed.
