2004 Jupiter 31 FS: Dual Mercury Verado Performance Fishing Platform in South Yarmouth
The 2004 Jupiter 31 FS represents a proven offshore fishing platform engineered for New England waters and beyond. Located in South Yarmouth, Massachusetts, this 31-foot center console combines the Jupiter brand's reputation for seaworthiness with a practical fishing layout and recently upgraded propulsion. At $159,000, the vessel offers established hull design paired with modern engine reliability and contemporary electronics integration.
Overview and Design Philosophy
Jupiter Marine built the 31 FS as a mid-sized fishing and cruising center console designed to handle the variable conditions of the Atlantic coast. The model's 9.5-foot beam provides stability and interior volume without sacrificing maneuverability in tight inlets or crowded anchorages. The 31-foot length positions the boat between day-running center consoles and larger overnight cruisers, making it suitable for extended fishing trips, family cruising, and coastal exploration where a cabin berth and galley support multi-day operations. The hull design emphasizes the nimble handling and responsive ride quality that Jupiter emphasized throughout its production years. The 31 FS was engineered to deliver comfortable transit in moderate sea states while maintaining the quick acceleration and tight turning radius expected from a modern center console. This balance between seaworthiness and agility defines the model's appeal to captains who value both offshore capability and day-to-day usability.
Propulsion and Performance
The recent engine upgrade significantly enhances the vessel's operational capability. The pair of Mercury 250 4.6L Verado outboards represent modern four-stroke technology with fuel efficiency and reliability advantages over older two-stroke alternatives. Mercury's Verado line is engineered for the 200–300 horsepower range and emphasizes low-end torque, smooth acceleration, and reduced emissions compared to carbureted or direct-injection competitors. With 500 total horsepower, the 31 FS gains responsive acceleration suitable for fishing operations—quick plane-off for reaching distant grounds—and efficient cruising at mid-range throttle settings. Mercury's 7-year factory warranty coverage through March 31, 2026, provides extended protection on the new powerplants and reflects the durability expectations of modern outboard engineering. The 310-gallon fuel capacity supports extended range operations typical of offshore fishing schedules. Dual outboards provide redundancy; if one engine requires service, the second remains available for return to port or continued operation at reduced speed. This reliability factor is particularly relevant for boats operating far from service facilities.
Helm and Electronics
The Simrad NSS16 Evo3 multifunction display represents a professional-grade chartplotter and sonar platform. The NSS16 Evo3 features a 16-inch high-resolution touchscreen, integrated CHIRP sonar capability, and compatibility with Navionics+ cartography, allowing detailed navigation, fish-finding, and waypoint management across the boat's operating grounds. Simrad's Evo3 interface emphasizes intuitive menu structures and real-time data overlay, critical for fishing applications where rapid adjustments to sonar settings and chart layers improve efficiency. The custom dash panel installation integrates the Simrad display into the helm layout with supporting controls for engine management, trim tabs, and accessory systems. This configuration allows the operator to monitor and adjust propulsion, steering, and fishing electronics from a single helm station, reducing the need to move about the boat during critical maneuvers or fish-finding sessions. The factory T-top provides weather protection and a platform for antenna mounting. The recent softtop canvas replacement ensures UV protection and water-shedding capability, extending the lifespan of the frame and improving operator comfort during extended time at the helm.
Fishing and Deck Layout
The 31 FS is configured as a dedicated fishing platform with features that support both offshore and inshore operations. The large in-deck fishbox provides insulated storage for the day's catch, maintaining temperature control and preserving fish quality throughout extended trips. In-deck boxes are integrated into the deck structure, offering more usable space than transom-mounted alternatives and reducing weight distribution issues. The livewell system maintains bait and smaller fish in circulated, aerated saltwater, essential for live-bait fishing and catch-and-release operations. A functioning livewell with reliable circulation is fundamental to modern fishing boat design, and the 31 FS's integration reflects the model's fishing-focused heritage. The center console layout positions the helm forward with 360-degree sightlines, a critical feature for spotting fish, navigating shallow water, and maintaining awareness during high-speed transits. The open deck aft of the console provides room for fighting chairs, rod storage, tackle organization, and crew positioning during active fishing.
Comfort and Cabin Accommodations
The Jupiter 31 FS includes a cabin with sleeping berth and marine head, supporting overnight cruising and extended fishing trips where returning to shore daily is impractical. The cabin layout typically includes a V-berth forward or a convertible seating-to-sleeping arrangement, depending on the specific configuration. A marine head with manual or electric operation provides essential sanitation facilities, and the cabin's headroom and ventilation support comfortable rest between fishing sessions or during weather delays. The integration of cabin and cockpit spaces in a 31-foot platform requires thoughtful design; the 31 FS achieves this by positioning the helm forward, the cabin amidships, and the open fishing deck aft, allowing crew to move between fishing operations and interior shelter without excessive congestion.
Structural and Cosmetic Updates
The freshly Awlgrip-finished outboard bracket reflects attention to corrosion prevention and aesthetic maintenance. Awlgrip is a two-part polyurethane coating system designed for marine aluminum and steel, offering UV protection and durability in saltwater environments. The new boot stripe—the contrasting stripe running along the hull's waterline—provides both visual definition and protective coating renewal. These cosmetic and protective updates signal ongoing maintenance and suggest the vessel has been managed with attention to long-term preservation. While cosmetic work alone does not indicate mechanical condition, the combination of new engines, recent canvas replacement, and hull refinishing demonstrates an owner commitment to the boat's operational readiness.
Electronics Integration and Customization
The broker notes that the vessel is ready for a custom electronics package, with professional installation available through the brokerage if desired. This flexibility allows a buyer to add autopilot, additional sonar transducers, VHF radio, engine monitoring systems, or other electronics tailored to specific fishing or cruising preferences. The Simrad NSS16 Evo3 provides a robust foundation; additional systems can integrate through NMEA 2000 networking or standalone installation.
Operational Suitability and Market Position
The 2004 Jupiter 31 FS occupies a practical niche in the used fishing and cruising boat market. The model's reputation for responsive handling and seaworthy construction, combined with the recent engine upgrade and electronics integration, positions the boat for serious fishing operations, coastal cruising, and family boating in New England and beyond. The 31-foot length and center console configuration appeal to captains who value maneuverability and open deck space, while the cabin and livewell satisfy the demands of extended offshore fishing schedules. The dual Mercury Verado upgrade and extended factory warranty reduce mechanical risk, a significant consideration in purchasing a 20-year-old hull. The Simrad NSS16 Evo3 and custom dash panel reflect modern electronics standards, eliminating the need for immediate avionics investment. This Jupiter 31 FS represents a well-maintained, mechanically refreshed offshore fishing platform ready for immediate use in professional or recreational applications. The combination of proven hull design, upgraded propulsion, contemporary electronics, and fishing-specific features supports confident operation in the demanding conditions typical of Atlantic coastal and offshore fishing.
