American Water Sports is proud to present this brand-new 2025 Harris Grand Mariner 250 - Harris's flagship 28-foot premium pontoon built in Fort Wayne, Indiana and powered by the segment-topping Mercury 400L Verado V10 outboard, finished in a striking Ceramic White and Black Sapphire exterior with the premium Pillow Chest Brown Cool Touch interior. Available at our Shell Knob location on Table Rock Lake (Stock #HA-GM25.25-P2822, Hull #HAMP2822I425), this Grand Mariner 250 sits at the top of the Harris pontoon hierarchy - Harris's flagship Grand Mariner line, sized at the larger 28-foot length that defines premium-flagship pontoon production, and configured with the absolute-top-of-line current-generation Mercury 400hp Verado V10 outboard. The Mercury 400L Verado is the headline powertrain story on this build: Mercury's flagship V10 4.6-liter naturally-aspirated outboard, the most-powerful single-engine outboard available in the premium-pontoon segment, delivering the kind of strong tow capability, high cruising speeds, and effortless passenger-loaded performance that only Mercury's flagship Verado V10 produces. As a Boating Industry Top 100 Dealer with full factory authorization and factory-trained Mercury service technicians on staff, American Water Sports offers the complete new-boat ownership experience from purchase through warranty service. For the premium-pontoon family who wants the absolute current-vintage flagship Harris build - paired with Mercury's flagship Verado V10 powertrain and the kind of factory color-and-trim spec that defines the upper tier of new-pontoon production - this Grand Mariner 250 is one of the more compelling new-boat opportunities at our Shell Knob location this season.
Why a 2025 Harris Grand Mariner 250?
Harris has been building premium pontoons since 1957 and is today owned by Brunswick Corporation - the same parent company that owns Mercury Marine, Lund, Bayliner, Boston Whaler, and a broad range of other premium marine brands - making Harris one of the most-resourced and most-supported premium pontoon manufacturers in the segment. The Grand Mariner specifically is Harris's flagship pontoon family, sitting at the top of the Harris hierarchy above the Cruiser, Sunliner, and value-tier lines. The Grand Mariner 250 designation indicates the larger 28-foot Grand Mariner platform - meaningfully more cockpit volume, more passenger capacity, more storage, and more useable interior space than the more-common 25-foot premium pontoons in the segment. As a 2025 model year build, this Grand Mariner 250 represents the absolute current-vintage Harris production - the most-recent design refinements, the most-current factory feature content, the most-modern wave-shaped tube architecture, and the kind of contemporary fit-and-finish that current-vintage premium-pontoon buyers expect when stepping up to a new build. For the premium-pontoon family cross-shopping current-vintage flagship builds - particularly comparing to comparable Bennington Q-Series, Barletta Reserve, and Manitou Encore competitors - this 2025 Harris Grand Mariner 250 represents Harris's strongest current production effort with full Brunswick/Mercury parent-company backing.
Mercury 400L Verado V10 - Flagship Outboard, Segment-Topping Power
Power on this Grand Mariner 250 comes from the Mercury 400L Verado V10 - Mercury Marine's absolute-flagship outboard and one of the most-powerful single-engine outboards available in the premium-pontoon segment. The Verado 400 is Mercury's V10 4.6-liter naturally-aspirated outboard (the bigger, more-powerful sibling to the V8 Verado 250/300 platform), producing 400 horsepower with the kind of broad torque curve, smooth power delivery, and refined cruising character that only Mercury's flagship V10 architecture produces. 400 horsepower on a 28-foot Harris flagship pontoon delivers truly meaningful real-world performance - the boat handles a fully-loaded passenger group with strong on-plane response, delivers comfortable cruising speeds across Table Rock Lake's bigger water, provides serious tow capability for tubing and skiing duty, and produces the kind of effortless authority that makes the larger 28-foot flagship platform feel remarkably nimble for its size. The Verado V10 is supercharger-free (vs the older Verado L6 supercharged platform) and delivers Mercury's most-current digital-throttle integration, joystick-piloting compatibility, smartphone connectivity through Mercury's app ecosystem, and the broadest possible Mercury dealer network parts and service support. As a Mercury-authorized dealer with factory-trained Mercury technicians, American Water Sports provides full Verado warranty service and the kind of brand-correct shop support that makes Verado V10 ownership straightforward.
Ceramic White / Black Sapphire Exterior with Pillow Chest Brown Cool Touch Interior
This Grand Mariner 250 was specified in a striking, premium factory color combination - Ceramic White exterior with Black Sapphire secondary graphics, paired with the premium Pillow Chest Brown interior in Harris's Cool Touch heat-reflective treatment. The Ceramic White and Black Sapphire exterior combination is one of the more visually-distinctive Grand Mariner color specifications - clean white pontoon and fence with deep, dark sapphire-black accent graphics, the kind of modern, premium presentation that defines current-vintage flagship pontoon styling. The Pillow Chest Brown Cool Touch interior is Harris's premium heat-reflective upholstery treatment - engineered to stay cooler in direct sun than darker upholstery colors (a meaningful comfort factor on Table Rock Lake summer days when boats sit at the dock or sandbar with full sun exposure) while maintaining the kind of warm, premium, modern interior aesthetic that Pillow Chest Brown delivers. The Cool Touch upholstery technology is becoming a near-mandatory feature on premium-pontoon production for serious lake-day buyers - the comfort improvement on hot-sun days is genuinely meaningful and the longer-term UV-resistance advantage protects upholstery condition over years of use. The factory color and trim spec on this Grand Mariner 250 sits in the premium, broadly-desirable, modern range - striking enough to be distinctive, tasteful enough to remain broadly appealing for future resale.
28-Foot Flagship Pontoon Layout - Maximum Premium Family-Day Versatility
The Grand Mariner 250's 28-foot platform delivers the kind of maximum-premium family-day pontoon footprint that defines the flagship 28-foot tier of the segment. Standard Grand Mariner 250 equipment from the 2025 vintage typically includes premium furniture (with Harris's premium stitching and upholstery treatments), premium deck-covering options (typically Harris's premium vinyl-deck offerings at this tier), premium fence/railing configurations with modern styling, premium helm electronics with marine GPS chartplotter and integrated multi-function display, premium audio system with multiple speakers and amplifier, premium navigation and accent lighting (including under-deck and color-shifting interior accent lights), Bimini or hard-top sun cover, integrated cup holders and storage throughout, ski-tow capability, and the kind of fit-and-finish that current-vintage flagship pontoon buyers cross-shop against current Bennington Q-Series, Barletta Reserve, and Manitou Encore alternatives. The 28-foot platform length is meaningfully larger than the more-common 25-foot premium pontoons in the segment - more passenger-capable, more storage-rich, more cockpit volume, and notably more comfortable on Table Rock Lake's bigger water on windier days. For specific factory option content, audio system spec, helm electronics configuration, and optional accessories on this specific 2025 Grand Mariner 250, please see the build specifics section below or contact our Shell Knob team.
New-Boat Advantages - Full Factory Warranty and Modern Service Support
As a brand-new 2025 model year build, this Grand Mariner 250 comes with the full factory new-boat warranty package - Harris's structural and limited-component warranty plus Mercury's Verado V10 factory warranty, both with the kind of full coverage that only new-boat ownership delivers. New-boat purchase also delivers several other meaningful advantages over pre-owned and brokered alternatives: the most-current factory feature content and design refinements, no service-history uncertainty, no cosmetic wear concerns, no upholstery patina considerations, no engine hour expectations, and the kind of factory-original presentation that current-vintage buyers specifically come looking for. As a Boating Industry Top 100 Dealer with full factory authorization for both Harris (through Brunswick Corporation parent) and Mercury Marine, American Water Sports provides the complete new-boat ownership experience: knowledgeable purchase consultation, factory-trained service support throughout the warranty period, and the kind of long-term dealer relationship that makes new-pontoon ownership straightforward. For the buyer who wants the new-boat experience with full warranty coverage and the most-current factory feature content, the 2025 Grand Mariner 250 is genuinely well-positioned in our Shell Knob inventory.
