Boston Whaler Conquest Boats For Sale

Boston Whaler Conquest boats span a pilothouse-style cabin range built around the brand's foam-filled, two-part hull construction, where closed-cell foam is injected at high pressure between the inner and outer molds. That process gives the line its reputation for staying afloat even when holed, and it shows in the finish too: gel coat covers the inside surfaces and hatch liners, not just the exterior. Across the 325, 365 and 405, these are dual-purpose hulls set up for offshore fishing and family cruising, with insulated fish boxes, pressurized livewells, dive doors and walkaround side decks alongside enclosed cabins suited to overnighting.

The Conquest 325 measures 32 feet 3 inches LOA with a 10-foot-8-inch beam, a 26-inch draft and a 10,500-pound empty weight, riding on a clean-sheet hull design. Power comes from twin Mercury 300, 350 or 400 outboards. Rigged with twin 350 Verados and 16-by-7 props at a 13,999-pound test weight, top speed reached 42.3 knots at 6,000 rpm, with a best cruise of 25 knots at 4,000 rpm burning 22 gallons per hour for 1.1 nautical miles per gallon and a 306.8-nautical-mile range off the 300-gallon fuel capacity, holding a 10 percent reserve. It planed at 10.7 knots in 5.2 seconds.

The Conquest 365 runs 36 feet 6 inches LOA on a 12-foot beam, with a 31-inch draft, 19-degree deadrise and a 19-gallon livewell. Dry weight is 17,603 pounds, rising to 23,447 pounds with engines and fuel, and capacity is 16 people. Fuel capacity is 410 gallons, water 52 gallons and waste 20 gallons, with a separate 50-gallon diesel tank for the onboard generator. With triple 400-horsepower outboards it reaches 55.7 mph top speed, cruises at 36.8 mph and returns 0.8 mpg for a 296-mile range. A separate run on triple Mercury 600 V12s recorded 53.1 mph at 6,400 rpm and a best cruise of 41.6 mph at 5,000 rpm getting 8 mpg, with 0-to-30 mph in 8.9 seconds. As of spring 2026, a Boston Whaler 365 Conquest was priced at $1,194,978.

The Conquest 405 is the flagship, available with quad outboards or triple Mercury 600-horsepower V12s, the setup that delivers low-end torque and a quiet cruise around 3,700-3,800 rpm and 27 knots. It carries two fuel tanks, a Fischer Panda diesel generator, 100 meters of galvanized chain on a stainless anchor with quick windlass, and a recorded peak speed of 53.3 knots. The aft cockpit can be ordered with a summer kitchen featuring a Kenyon electric grill, Corian counters, a sink and a pull-out drawer refrigerator, with a Seakeeper gyro and through-hull fittings grouped under a single hatch.

Shoppers comparing Boston Whaler Conquest boats for sale will find shared systems across the range: Simrad or Raymarine glass-cockpit displays, Mercury joystick and DTS controls, Seakeeper gyro stabilization, heading-hold autopilot, and diesel generators driving 16,000-BTU air conditioning. The 365 and 405 offer a full Pilot House glass enclosure option and below-deck cabins with forward and aft berths near queen size, a full head with shower and a galley. Point-of-use storage, recessed cleats, spring-loaded fender holders and concealed telescopic swim ladders carry through the line.
