Cobalt 336 Boats For Sale

The Cobalt 336 is a 33-foot bow rider with a small cabin below, built to work as a day boat that can also handle an overnight stay when weather turns or a trip runs long. Overall length runs about 34 feet 9 inches with a 10-foot 6-inch beam, a 9-foot interior cockpit width, and a 22-degree deadrise hull. Fuel capacity is 174 gallons. Cobalt introduced the model in its 2013 lineup and carried it through model years including 2014 and 2016, pairing a twin-engine stern drive package with a full cuddy cabin and head.

Power is twin sterndrive, and the 336 was offered with several engine choices. One configuration ran twin MerCruiser 8.0-liter Axius Bravo 3 drives turning 24-inch Bravo 3 props; with a test load of 235 pounds of passengers and 75 gallons of fuel, that setup reached a top speed of 53.6 mph at 5,000 rpm. The most economical cruise came at 33 mph and 3,000 rpm, returning 1.51 miles per gallon. Other 336s were built with twin MerCruiser 377 Mag drives at 320 horsepower per side, twin Mercury 8.2 Mags at 380 horsepower each, or twin Volvo Penta 380-horsepower V8s. Trim tabs and underwater lighting were common equipment.

The helm centers on a fiberglass console with instruments set in aluminum panels to keep their seals over the life of the boat, stainless steel switches, and a double-wide seat with a flip-up bolster. MerCruiser-powered boats carried the Axius joystick docking system with SmartCraft gauges, Medallion digital instruments, and on later boats a Garmin 741 touchscreen GPS, VesselView, SkyHook station holding, a Kicker stereo, and VHF. Volvo Penta boats used Volvo's auto-docking system to maneuver without bow or stern thrusters and a Raymarine display.

The transom uses Cobalt's patented swim step, a platform that drops into the water and folds away, with stainless steel guarding around the platform and a walk-through to the cockpit. A convertible sun pad sits aft over wet storage for fenders and lines, and many boats carry a transom grill mount. The cockpit holds an entertainment galley with a microwave, a refrigerator or icemaker, a stainless sink with a hard-surface countertop, a cutting board, a trash bin, and GFI and TV outlets. A table stows quickly on a hidden bracket, the engine hatch lifts on hydraulics for access to the V8s, and battery switches sit under a seat. Fender clips let crew move fenders side to side by button.

Down below, the cabin includes a flat-panel TV, air conditioning and heat, and a stereo system, with a lounge that converts to a full-size berth sleeping two. The head compartment has a pump-out or electric toilet, a solid-surface sink, hot and cold shower, and headroom suiting someone up to roughly 6 feet 4 inches, with a board over the toilet for use as a changing room. Walk-through doors close the bow off from the cockpit. The bow seats a double-wide lounge to starboard and a single to port with armrests, and a windlass with a stainless anchor handles ground tackle.

Cobalt builds the 336 with all hand-laid fiberglass, no wood and no chop, and leaves hulls in the mold six days for the finish. There is no trim tape; the color is in the gel coat, so there is no tape to mar. Buyers can option a stainless steel radar arch with hardtop or a bimini, plus a generator, air conditioning, SureShade, and premium audio such as Rockford Fosgate or JL Audio. When shopping a used Cobalt 336 for sale, confirm which engine package is fitted, since the choice between the 320-horsepower and 380-horsepower options changes performance, and check the gel coat finish, swim step mechanism, and hydraulic engine hatch.
