Buyer questions
Eight questions buyers ask about the G3 Bay 21 GX, answered from the boats listed on US Marine Connection right now.
Right now US Marine Connection shows 7 approved, priced G3 Bay 21 GX listings asking between $51,025 and $52,813, with a median asking price of $52,579. Those are asking prices, not recorded sale prices. The spread is tight because all seven are the same model year and similarly equipped, with differences mostly in engine choice and color. All seven listings include photos.
Every Bay 21 GX currently listed on US Marine Connection is a 2027 model. All 7 priced listings fall in that single year, so there is no older used inventory to compare against on the site at the moment. If you want earlier years in the G3 family, the Sportsman 1710 listings span 2019 through 2027, which is the widest year range among the siblings shown.
None of the 7 Bay 21 GX listings on US Marine Connection states an engine hour figure, so there is no typical number to quote here. What the listings do show is the year (all 2027), the Yamaha outboard model on each boat, the trailer, the color and the stock number. If hours matter to you, ask the seller directly and confirm the reading on the engine gauge or diagnostic readout.
Since the listings give the engine model but no hours, start there: have the Yamaha outboard scanned for hours and fault codes, and check the lower unit oil and water pump service history. Confirm the trailer, listed as an EZLOADER or Bear Bay 21, has sound bearings, tires and lights. On a bay-style center console, look over the deck, hatches, livewell plumbing and steering, and match the hull and stock number to the paperwork.
The descriptions on US Marine Connection are short and spec-focused. Each Bay 21 GX is a center console measuring 21 ft 4 in, paired with a Yamaha outboard, listed as a VF175LB, VF150LB or F150LD depending on the boat, and delivered on a trailer, either an EZLOADER Bay 21 or a Bear Bay 21. Colors listed include Sharkskin Gray, Arctic Blue and Black. Anything beyond that is not stated, so confirm equipment with the seller.
The facts here point that way. Every listing is a center console, the layout most buyers choose for fishing because it lets you work bait and rods around the whole boat. At 21 ft 4 in with Yamaha outboard power and a matched bay trailer, it is set up for trailering to the ramp. Specific fishing gear such as livewells or rod storage is not named in the descriptions, so confirm what each boat has.
All 7 priced Bay 21 GX listings on US Marine Connection are in Houston, Texas, and all 7 include photos. There is no other city showing this model at the moment. If you are outside Texas, the listings are still worth reviewing by stock number and engine, since each one specifies the Yamaha outboard, the trailer and the color before you contact the seller.
Mainly price and size within the same bay family. The Bay 21 GX lists from $51,025 to $52,813, median $52,579, across 7 boats, all 2027. The Bay 20 shows 9 listings at $36,850 to $37,364, median $37,010, also 2027. The Bay 18 shows 11 listings at $32,783 to $33,364, median $33,125, 2027 as well. Feature-level comparisons are not possible from the descriptions, which list engine, trailer, length and color only.
