Sea Ray 340 Sundancer Boats For Sale

The Sea Ray 340 Sundancer is a 34-foot express cruiser built by Brunswick Marine, with a single forward cabin, a wet head, a galley, a salon seating area, and a second sleeping berth aft beneath the cockpit. Produced across the early-to-mid 2000s, it shows up on the used market in 2002, 2005, 2006 and 2007 model years, often listed for sale by owner. It suits a couple cruising and island-hopping or a family of four to six taking the kids or grandkids out for a weekend, and at this size it feels like a larger yacht without being intimidating to handle.

Most Sea Ray 340 Sundancers run twin gasoline inboards on a V-drive setup, which seats the engines aft and improves low-speed maneuverability. Power options seen across the years include MerCruiser 7.4-liter 454s rated around 320 horsepower each, 6.2-liter engines, Mercury 370-horsepower V-drives, and the larger Mercury MerCruiser 8.1 Horizon engines. On the 7.4-powered boat, sustained cruise averaged 19 to 22 mph, roughly 20 knots. These are gas boats by design; a diesel 340 Sundancer is uncommon, since diesel would have raised the price considerably. The 6.2-liter version is regarded as the more economical choice for fuel consumption. Some boats add a bow thruster, which makes docking notably easier.

The dual-seat helm sits to starboard, each seat with a flip-up bolster, under eisenglass enclosure with an electric vent for airflow. Equipment varies by boat and is frequently updated, with Garmin or Raymarine chart plotters, a Garmin autopilot and hydraulic pump, VHF radio, SmartCraft or electronic engine readouts, trim tab and electric engine-hatch controls, and radar on some listings. An electric windlass with foot switches at both the bow and the helm, plus a controllable spotlight, handle anchoring.

The cockpit carries U-shaped or wraparound seating with a removable table and a fill-in cushion that converts the area into a sun bench. An aft bimini and a full camper canvas enclosure let the space be used in rain, wind or sun, an accessory not every 340 carries. To starboard is a wet bar with a deep sink, plus a refrigerator or a slide-out stowaway cooler, a trash bin and cup holders. The wide swim platform has a transom shower and boarding ladder, many boats are finished in SeaDek, and the foredeck offers a large bow sun pad, skylights and an escape hatch.

Down four steps, the interior places the galley to port with a stainless microwave-convection oven combo, a two-burner electric cooktop with a cover, a deep stainless sink and a mini-fridge or Isotherm refrigerator with a freezer compartment. The forward cabin holds an island queen berth with steps on both sides and the air-conditioning unit beneath the mattress. The salon couch and pedestal table convert to a dinette and an additional berth, the aft mid-cabin sleeps two more under the cockpit, and the wet head uses a VacuFlush system with a telephone-style shower faucet. Storage is generous throughout, with drawers, cabinets and overhead lockers, and some boats add TVs including a drop-down screen.

For anyone weighing a Sea Ray 340 Sundancer for sale near them, build inspection matters. The interior structure, stringers and deck use plywood and balsa coring glassed over, which can rot if moisture intrudes, so check the foredeck below hatches with a moisture meter. The cast-iron exhaust manifolds on the Mercury gas engines are a known weak point and should be replaced about every three years to avoid water leaking into a cylinder. Dry-rotted waste and raw-water hoses are common on early-2000s examples, shaft seals should be checked both at the dock and underway, and factory and aftermarket wiring can be sloppy. On the used market, one well-equipped 2001 with freshly remanufactured engines, new canvas, generator and electronics was offered around the mid-$80,000s.
