2018 Sea Ray 350 Sundancer Coupe
This exceptionally well-maintained 2018 Sea Ray 350 Sundancer Coupe offers an outstanding combination of luxury, performance, and all-season comfort. A two-owner vessel, she has been professionally serviced by a Sea Ray/MerCruiser dealer since new and reflects a high level of pride of ownership.
Powered by twin MerCruiser 6.2L MPI engines with Axius joystick drives, this Sundancer delivers effortless docking, confident handling, and an enjoyable cruising experience. With just 459 engine hours, she has also received a substantial investment in major engine and sterndrive maintenance, including extensive mechanical work completed in 2026.
Extensive Engine & Mechanical Work Completed in 2026
A significant amount of major maintenance and preventive work has recently been completed on both engines and drive systems, providing the next owner with considerable peace of mind:
- New exhaust manifolds, risers, and exhaust flappers on both engines
- New drive gimbal bearings
- New sterndrive U-joint bearings
- All four top-end head gaskets replaced
- New engine cooling water pumps on both engines
- Upgraded raw-water cooling systems on both engines
- Dedicated 1¼" thru-hull raw-water pickups added for both engines
- New cooling-water configuration bypasses the sterndrive water pickups, providing a more direct and reliable source of cooling water
- The upgraded system also helps reduce cooling restrictions associated with barnacle and marine-growth buildup within sterndrive water pickups
- All new canvas and isinglass installed in 2025
This represents a substantial investment in some of the more significant maintenance items associated with the engines and sterndrives. The upgraded raw-water cooling system is an especially valuable improvement for a boat operated in salt water, providing a dependable source of cooling water while reducing reliance on the sterndrives' integrated water pickups.
Helm & Electronics
The helm received a significant electronics upgrade at the end of the 2023 season, featuring Garmin GPSMAP 1243xsv multifunction displays and a Garmin Fantom 24X solid-state radar. These systems are complemented by the factory Mercury VesselView Digital Dash, providing comprehensive monitoring of engine performance and vessel systems.
Comfort & Accommodations
Inside, the spacious coupe configuration provides a bright, comfortable environment that works equally well for weekend cruising, extended stays aboard, or entertaining family and friends. The open cockpit transitions naturally into the salon, creating an inviting and versatile living space.

Sea Ray Sundancer 350 Coupe: BoatTEST Review
Overview
The Sea Ray Sundancer 350 Coupe represents the largest model in Sea Ray's sport cruiser lineup, designed with dual-purpose flexibility for both day boating and overnight cruising. This model distinguishes itself from the standard Sundancer 350 by featuring a fully enclosed helm with a solid windshield and side windows integrated into the hardtop, enhancing protection from the elements and allowing for optional climate control.
Power and Performance
Measuring 37 feet 6 inches in length overall with a beam of 11 feet 4 inches, the Sundancer 350 Coupe carries 214 gallons of fuel in twin saddle tanks. Our test boat, weighing approximately 20,039 pounds with fuel and three passengers aboard, was equipped with optional twin 380 horsepower Mercury 8.2-liter Mag ECTC engines paired with Bravo 3X drives. This configuration achieved a top speed of 36.8 miles per hour at 4750 rpm and an optimal cruising speed of 31 mph at 4000 rpm, where fuel consumption was 40.5 gallons per hour, yielding a range of 147 statute miles while maintaining a 10% fuel reserve. Acceleration to plane occurred in 6.8 seconds, with 20 mph reached in 11.9 seconds and 30 mph in 21.7 seconds. Handling characteristics included a somewhat elevated bow attitude at speed and a higher center of gravity, but the boat demonstrated a dry ride crossing wakes by effectively dispersing spray. Maneuvering was notably precise, especially with the optional bow thruster and Axius joystick propulsion system, which greatly simplified docking and close-quarters handling.
Exterior Design and Deck Features
The Sundancer 350 Coupe’s exterior emphasizes functionality and comfort. The helm station is situated at the forward end of the enclosed cockpit area, featuring a double-wide bench seat with a flip-up bolster and swivel capability to engage with cockpit guests. Visibility is enhanced by a single-piece windshield with pantograph wipers and vent side windows. The cockpit itself offers an L-shaped settee with a high-low pedestal table, available in fiberglass or optional solid wood, complemented by a starboard settee with a built-in refrigerator and an optional flat-screen TV on a swivel mount. Overhead, a powered sunroof measuring five feet wide by nearly three feet fore and aft provides natural light and ventilation, with a positive close to prevent water intrusion. Additional shading is available via an optional motorized retractable awning over the cockpit table. The swim platform includes a built-in electric grill, stainless steel sink, and prep counter with storage drawers beneath. Options include an extended teak swim platform and an electrically actuated swim step. Safety and convenience features include recessed mooring cleats, courtesy lighting, and well-placed handrails along the narrow six-inch side decks leading forward to a sun pad with adjustable backrests and a recessed anchor station equipped with a gas-shock-assisted windlass cover and a cleat to relieve anchor load.
Engine Room and Mechanical Systems
Accessed via an electrically actuated hatch under the aft deck, the engine room houses the twin Mercury 8.2-liter big block engines, the largest available for this model. Maintenance features include starboard-side oil dipsticks, dedicated oil filter drip trays, and front-mounted coolant reservoirs. A clear serpentine belt routing diagram is provided for ease of service. The generator is centrally located forward of the engines, and battery terminals are protected with rubber covers. The installation meets ABYC standards with double hose clamps on exhaust risers and raw water pickups, and the generator’s bronze raw water pickup is properly bonded and secured.
Interior Living Spaces
Below deck, the companionway features four wooden steps with non-skid inserts and offers 6 feet 4 inches of headroom. Owners may select between cherry or pecan wood finishes with matching wood soles. The galley, located to starboard, is equipped with a microwave, induction cooktop, solid surface countertops, and a refrigerator. While the cabin side windows are fixed, optional opening ports can be added for ventilation. Forward and to port, an L-shaped settee surrounds a removable dining table, with storage and a woofer beneath the forward seat. A loveseat with a sliding mechanism converts into additional sleeping bunks, complemented by a privacy curtain for overnight accommodations. The master stateroom forward features an angled berth with overhead storage lockers, a hatch for natural light and ventilation, and a hanging locker that separates it from the port settee, which faces a 32-inch flat-screen TV.
Private Accommodations and Heads
The head compartment is located to port of the accommodations ladder and includes a vacuum-flush toilet, a separate shower stall with a glass door, a vessel sink set in a solid surface countertop, and both a power vent and an opening port for ventilation. The standard layout includes a separate guest cabin aft of the accommodations ladder with twin 6-foot 4-inch bunks that can be combined into a double berth, a small settee, hanging locker, and storage lockers. An alternate layout replaces the twin berths with an L-shaped convertible seating area. Opening ports on both sides provide natural light and fresh air. Overall, the Sundancer 350 Coupe can comfortably sleep up to six guests.
Conclusion
The Sea Ray Sundancer 350 Coupe is a versatile sport cruiser that balances day boating enjoyment with comfortable overnight accommodations. Its enclosed helm and optional climate control systems allow for use in varied weather conditions, while its thoughtful design emphasizes entertainment and ease of handling. With ample interior space, flexible sleeping arrangements, and well-considered exterior amenities, the 350 Coupe is well suited for those seeking a capable and comfortable cruiser that performs reliably and offers a refined onboard experience.
