Buyer questions
Eight questions buyers ask about the G3 Bay 21 GX Tunnel, answered from the boats listed on US Marine Connection right now.
Right now US Marine Connection shows four priced Bay 21 GX Tunnels, and all four are listed as new 2026 units rather than used. Asking prices run from $49,437 to $51,210, with a median of $50,032. Those are asking prices, not recorded sale prices. Each listing includes an EZ Loader trailer and a Yamaha outboard, so the price covers more than just the hull.
Every Bay 21 GX Tunnel currently listed is a 2026 model year. There are four of them, all described as new units, and all four have photos. No older model years show up on the site for this boat at the moment, so if you are after an earlier build there is nothing listed here to compare against right now.
None of the four listings states an engine hour figure, so there is no honest number to give you. All four are described as new 2026 units, which suggests little to no runtime beyond dealer testing. If hours matter to you, ask the seller directly and confirm what the Yamaha F150LD or VF175LB gauge or diagnostic readout actually shows before you commit.
Since these are 2026 aluminum center consoles listed as new, focus on delivery condition: hull and welds for shipping dings, transom fit at the Yamaha F150LD or VF175LB, and that rigging, steering and gauges all work. Confirm the Yamaha warranty start date and registered hours. The included EZ Loader trailer deserves its own look, tandem axle on at least one unit, so check bearings, lights, tires and title paperwork.
The listings keep it brief. Each is an aluminum center console with a 21 foot LOA and a tunnel hull, powered by a Yamaha outboard, either an F150LD on three of them or a VF175LB on one. All four include an EZ Loader trailer, with one specified as tandem axle. Anything beyond that, such as electronics or seating packages, is not named in the descriptions, so ask the seller.
The setup points that way. It is a 21 foot aluminum center console with a tunnel hull, a layout built for walking the deck and working lines around the boat, and the tunnel design is associated with shallow bay running. The listings do not detail rod storage, livewells or casting decks, so confirm the fishing package with the seller rather than assuming it is included.
All four Bay 21 GX Tunnels on US Marine Connection are in Houston, Texas. There are no listings in other cities for this model right now, so buyers elsewhere would be looking at a trip or arranging their own haul. Each of the four has photos, and all include a trailer, which makes taking one home under your own truck straightforward.
Mainly size and price. The Bay 21 GX Tunnel runs $49,437 to $51,210, median $50,032, all 2026 units. The Bay 17 shows three listings, all 2026, all asking $31,293. The Sportsman 1710 has four listed from $22,999 to $32,600, median $32,600, spanning 2019 to 2026, so it is the only one of the three where older boats are currently available. Detailed feature comparisons are not in the descriptions.
