2007 Master Craft X-80 STS — Twin MCX 5.7 | 700 HP | Loaded | Rack Stored 15 Years
Rare opportunity to own Master Craft's flagship twin-engine platform — the X-80 STS — at a fraction of new-boat cost. This 28-foot luxury wake/ski/surf boat has been rack stored in a heated facility for 15 years, a storage history that speaks directly to the care and preservation of the hull, upholstery, and mechanical systems. With only 599 hours on the twin Indmar MCX 5.7 engines, this boat has been lightly used relative to its age and is loaded with significant owner-invested upgrades.
The X-80 is Master Craft's only twin-engine model in the lineup — a distinction that gives it exceptional low-speed maneuverability for docking and handling, plus the power reserve to pull multiple riders, cruise comfortably, and run all day. The spacious cockpit accommodates family and friends with ease, and the onboard amenities — bathroom/changing room, sink, built-in fridge and cooler — make full-day outings genuinely comfortable.
The seller has invested heavily in audio, electronics, lighting, and cosmetics. The stereo system alone is a standout: a new Fusion head unit, two 12" subwoofers, four 8" tower speakers, and six 6" cockpit speakers, all with separate tweeters, blue LED light rings, and custom aluminum billet grilles. Custom cockpit and underwater lighting, a Raymarine GPS/chartplotter/fishfinder, and freshly installed factory gauges and control panels round out the package. The trailer has also been fully refreshed with new rims, tires, brakes, brake lines, bunk carpet, and hook chains.
KEY FEATURES:
- Twin Indmar MCX 5.7 Inboard Engines (700 HP Total, 599 Hours) — The twin-inboard configuration is what sets the X-80 apart from every other Master Craft model. Twin inboards provide independent thrust on each side, making low-speed docking and maneuvering significantly more controlled than a single-engine setup — a real advantage on a 28-foot boat. At 599 hours, these engines are well within their service life for a boat of this vintage.
-
- 15 Years of Heated Rack Storage — This boat spent its life out of the elements in a climate-controlled rack facility, which dramatically reduces the UV degradation, freeze-thaw stress, and hull osmosis risk that plague boats stored outdoors or in the water. For buyers, this storage history is one of the most meaningful indicators of long-term hull and upholstery condition available.
-
- Comprehensive Audio Upgrade — Fusion stereo, twin 12" subs, four 8" tower speakers, six 6" cockpit speakers, all with custom aluminum billet grilles and LED accent lighting. A properly spec'd marine audio system transforms on-water entertainment, and this installation goes well beyond factory spec.
