This 2005 Sea Ray 340 Sundancer is an exceptionally well-equipped two-owner, always freshwater vessel that has been well maintained and upgraded over the years. Powered by twin MerCruiser 8.1L Horizon MPI V8 inboard engines producing 370 HP each, this 340 Sundancer has only approximately 293 hours.

Even better, both engines have had the MerCruiser Cool Fuel updates completed.

Major recent upgrades include an all-new 2025 Raymarine electronics package featuring dual Raymarine displays, radar, autopilot and VHF radio. The boat also comes with new Isinglass windows that are still in the wrapper and a custom bow-to-stern winter cover.

Factory equipment includes a Kohler 5.0 kW generator, SmartCraft System View, premium cabin sound system, Sirius satellite radio, stainless-steel windshield frame, central vacuum and numerous other upgrades.

Finished with a beautiful blue hull, this is an impressive example of one of Sea Ray's most popular express cruisers and an excellent choice for Lake Michigan and Great Lakes cruising.

One of the biggest highlights of this 340 Sundancer is its highly desirable big-block power package:

Twin MerCruiser 8.1L Horizon MPI V8 Engines
370 HP Each / 740 Total Horsepower
V-Drive Inboard Propulsion
Only Approximately 293 Hours
Cool Fuel Updates Completed on Both Engines

The 8.1L Horizon engines provide the torque and power well suited to a cruiser of this size, while V-drive inboard propulsion provides a proven drivetrain configuration for larger express cruisers.

With only approximately 293 hours, the engine hours are particularly noteworthy for a 2005 model-year boat.

This Sea Ray has had only two owners and has always been a freshwater vessel.

For buyers shopping nationally for a pre-owned cruiser, freshwater history can be particularly desirable. This boat has spent its life away from the corrosive saltwater environment and has been well maintained with numerous upgrades.

Its history and equipment make it particularly worthy of consideration for someone searching for a quality freshwater Sea Ray 340 Sundancer.

Unlike many boats of this vintage that still rely primarily on their original navigation equipment, this 340 Sundancer received a significant electronics upgrade in 2025.

The new system includes:

• Dual Raymarine Multifunction Displays
• Raymarine Radar
• Autopilot
• VHF Radio

This modern electronics package is a major upgrade for navigation and cruising and adds significant value compared with an otherwise comparable 340 Sundancer still equipped solely with original-generation electronics.

The boat's original factory equipment also includes SmartCraft System View for twin engines and a systems monitor panel.

The boat was factory equipped with a Kohler 5.0 kW 120V/60Hz gasoline generator.

Having onboard generator power significantly expands the 340 Sundancer's cruising capabilities, allowing the use of important AC-powered systems while away from shore power.

Combined with the boat's air conditioning and comfortable cabin accommodations, this makes the 340 well suited for weekends aboard, anchoring out and extended cruising.

Another noteworthy upgrade is a set of new Isinglass windows that are still in the wrapper.

Clear enclosure panels can make a tremendous difference in the appearance of an older express cruiser while also providing important protection from wind, spray and cooler weather.

Having a brand-new set ready for installation is a valuable addition for the next owner.

For off-season protection, this boat includes a custom winter cover that extends from bow to stern.

For a Great Lakes boat, where proper winter storage and protection are especially important, a quality full-boat winter cover is an excellent addition.

The boat also includes its factory cockpit cover.

The Sea Ray 340 Sundancer was designed around outdoor entertaining.

Its generous cockpit provides plenty of room for family and friends whether cruising, relaxing at the dock or spending the afternoon at anchor.

Factory equipment includes a sun pad with headrest and stainless-steel deck runners, along with a second stereo remote at the transom.

The distinctive blue hull and upgraded stainless-steel framed windshield give the boat the classic premium Sea Ray appearance that continues to look sharp today.

Below deck, the 340 Sundancer provides the amenities expected from a genuine express cruiser, with comfortable spaces for relaxing, entertaining and overnight stays.

Factory equipment includes a premium 12-volt cabin sound system, upgraded entertainment equipment and a Beam central vacuum system.

The boat's air conditioning, generator and shore-power capabilities make extended stays aboard considerably more comfortable.

Finding an older cruiser is easy. Finding one with low hours, freshwater history, documented upgrades and desirable big-block power is considerably more difficult.

That's what makes this 2005 Sea Ray 340 Sundancer especially appealing.

It has had only two owners, has always been a freshwater boat and shows approximately 293 hours on its twin 8.1L Horizon engines. Both engines have received the Cool Fuel updates, and the boat has continued to receive meaningful upgrades rather than simply relying on its original equipment.

The 2025 dual-screen Raymarine electronics package with radar, autopilot and VHF is a particularly significant improvement for anyone planning to cruise Lake Michigan or the Great Lakes.

Add the Kohler generator, new Isinglass still in the wrapper, custom bow-to-stern winter cover, blue hull and extensive factory equipment, and this becomes a very compelling 340 Sundancer.

For buyers searching for a 2005 Sea Ray 340 Sundancer for sale, freshwater Sea Ray 340, low-hour Sea Ray Sundancer, Sea Ray with 8.1L Horizons, Sea Ray 340 with generator, used Sea Ray cruiser, Lake Michigan cruiser or Great Lakes express cruiser, this boat deserves serious consideration.

Whether you're planning weekend trips along the Lake Michigan shoreline, crossing the lake to favorite ports, entertaining friends at the dock or spending weekends aboard, this 340 Sundancer delivers the space, power and cruising amenities that made the Sundancer name so popular.
