Cobalt 336

This 2015 Cobalt 336 (R35) represents the perfect balance of performance, luxury, and versatility — a flagship day cruiser with the power and refinement to handle serious water. Cobalt’s reputation for exceptional build quality is on full display here: deep-V hull design, flawless fit and finish, timeless styling, and a ride that feels as solid at 20 knots as it does at 50.

This particular 336 has been freshwater kept since new, stored under cover, and meticulously cared for. It has low hours on its twin Volvo Penta V8-430 CE engines paired with Volvo Ocean X DPS-B Duo-Prop drives, the most desirable and powerful configuration offered for this model. Joystick docking makes close-quarters maneuvering simple and precise, while the 860 horsepower powertrain delivers smooth cruising at 35–40 mph and exhilarating top speeds north of 55 mph. This is truly a captain’s boat — powerful, quiet, and confidence-inspiring.

Performance & Mechanical Highlights:

• Twin Volvo Penta V8-430 CE engines (860 total HP)
• Volvo Ocean X DPS-B Duo-Prop outdrives with stainless props
• Volvo EVC with joystick docking system
• Digital helm displays with full engine diagnostics and fuel flow data
• Power steering, trim tabs, and power engine hatch lift
• Five AGM batteries (3 house / 2 starting) with smart battery management
• Shore power system with charger and breaker panel
• Freshwater closed-cooling engines — excellent for longevity

This setup was engineered to deliver exceptional acceleration, quiet mid-range cruising, and easy handling at any speed. With joystick control, docking is stress-free — even single-handed.

Comfort, Layout & Accommodations:

The 336 is renowned for its social layout — designed to bring people together while still offering room to move. Forward, the open bow features wraparound seating with ergonomic backrests, creating a true conversation pit. Aft, the signature convertible sun lounge offers multiple positions, from upright bench seating to a fully flat sunbed overlooking the swim platform.

• Open bow lounge with wraparound seating
• Convertible aft sun pad with multiple positions
• Enclosed head compartment with electric flush toilet, vanity sink & shower
• Below-deck cabin with wraparound leather sofa that converts to berth (sleeps 2+)
• Panoramic hull windows and overhead lighting
• Wet bar station with stainless sink and refrigerator
• Snap-in seagrass flooring in cockpit
• Ample storage throughout

It’s an ideal layout for entertaining, day cruising, or overnight trips. The build quality is unmistakably Cobalt: solid hardware, hand-stitched upholstery, and a quiet, smooth ride even at speed.

Navigation & Audio Systems:

This boat is upgraded with a Garmin Echomap 106sv touchscreen GPS/chartplotter for reliable and intuitive navigation. For entertainment, it features a Fusion 670 head unit paired with an JL Audio premium M6 system:

• Garmin Echomap 106sv touchscreen GPS/chartplotter
• Fusion 670 head unit with NMEA integration
• Eight JL Audio M6 coaxial speakers with RGB LED lighting
• Two 10″ JL Audio subwoofers with LED lighting
• JL amplifiers with zone control
• Integrated lighting control for audio zones

The sound system is clear, powerful, and fully integrated into the boat’s layout, creating a premium onboard experience whether at anchor or underway.

Deck & Hull:

• LOA: 34′ 9″ | Beam: 10′ 7″ | Draft: 2′ 11″ | Deadrise: 22°
• Extended swim platform with stainless ladder
• Hot & cold transom shower
• Transom door to cockpit
• Stainless steel hardware throughout
• Bow walk-through windshield
• Cockpit arch / Bimini top
• Anchor locker with windlass (all chain rode)
• Full cockpit and bow covers
• Ocean X corrosion-resistant outdrives
• Stainless ski tow eye
• Fender storage lockers and rope access points
• The deep-V hull provides a confident, dry ride and handles big water exceptionally well. Cobalt’s construction is second to none — this is a hull designed to perform and last.

Ownership Notes:

This boat has been freshwater only, gently used, and always maintained to high standards. It has low engine hours, a robust AGM battery bank, and premium upgrades throughout. It has never been neglected, never run in saltwater, and is in excellent overall condition.

For those who know the Cobalt brand, this is the configuration everyone looks for: 430 HP Volvo Ocean X + Joystick, a Garmin navigation suite, and a JL/Fusion premium audio system. Whether your plans involve entertaining friends, cruising the Great Lakes, or weekend overnights at the marina — this 336 delivers.

Freshwater since new
Low hours — meticulously maintained
Top power package with joystick docking
Premium Garmin & JL Audio upgrades
Five AGM battery system for extended on-the-water time
