Buyer questions
Eight questions buyers ask about the Boston Whaler 405 Conquest, answered from the boats listed on US Marine Connection right now.
On US Marine Connection right now there are three priced 405 Conquest listings, asking from $998,995 up to $2,222,808, with a median asking price of $1,299,995. Those are asking prices, not what anyone paid. The spread reflects a mix of a new 2027 boat with triple Mercury V12 600s and lightly used 2022 and 2023 hulls, so compare year, engine package and hours before reading much into the range.
The current listings run from 2022 to 2027, covering three boats. One is a new 2027 with zero engine hours, and the others are a 2022 and a 2023 that have been used. All three are listed as cruiser or yacht type with fiberglass or composite hulls. If you want an older hull than 2022, nothing like that is listed on US Marine Connection at the moment.
Two of the three descriptions state hours: 155 on the 2022 and 90 on the 2023, so a median of 90. The third boat is a new 2027 listed with zero hours. That is a small sample, so treat it as what is on the site rather than a rule. For any boat where hours are not stated, ask the seller for the engine readouts and service records in writing.
These are 2022 to 2023 boats with real hours, 155 and 90 in the two used listings, so start with the Mercury outboards: the 600 V12 and 400 V10 packages here need full diagnostic downloads, service history and warranty status confirmed. Check the fiberglass hull and gelcoat, transom and rigging, all electronics and pumps, and run everything at the dock and under way. A survey and sea trial are worth it at these prices.
Going only by what the listings state: the new 2027 has triple Mercury V12 600 outboards totaling 1800 horsepower, a white hull and fiberglass or composite construction. The 2022 is 41 ft 4 in with a 13 ft 6 in beam, white, with Mercury 600 V12 power rated 1800 horsepower. The 2023 is about 41 ft with the same beam, platinum color, and Mercury 400 V10 power at 1600 horsepower. Other equipment is not detailed, so ask the seller.
The listings support it as an offshore-capable boat: all three are cruiser or yacht type, around 41 feet with a 13 ft 6 in beam, fiberglass or composite hulls, and heavy outboard power at 1600 to 1800 horsepower. That is a lot of range and running ability for open water. The descriptions do not spell out tackle storage, livewells or cabin layout, so confirm the specific offshore and overnight gear with the seller.
The three listed on US Marine Connection are in Seattle, Washington, which accounts for two of them, and Grasonville, Maryland, which has one. The two Washington boats are the 2022 and 2023 used examples, and the Maryland boat is the new 2027 with triple V12 600s. With only three nationwide on the site, expect to travel or arrange transport rather than find one in your own harbor.
Price is the clearest difference in the current listings. The 405 Conquest asks $998,995 to $2,222,808, median $1,299,995, across 2022 to 2027 cruiser or yacht listings. Three 420 Outrage boats are listed from $450,000 to $1,164,000, median $994,595, years 2016 to 2025. Three 250 Outrage boats run $72,000 to $310,169, median $154,995, years 2011 to 2027. The 405 is the enclosed cruiser of the group; the Outrages are center console layouts.
