Boston Whaler 405 Conquest 2022 vs Boston Whaler 420 Outrage 2022 — Same Brand, Different Boat

The Boston Whaler 405 Conquest 2022 vs Boston Whaler 420 Outrage 2022 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The power gap is worth calling out. Rated to 600 hp, the Boston Whaler 420 Outrage 2022 has a 300-hp advantage over the Boston Whaler 405 Conquest 2022's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Boston Whaler 405 Conquest 2022 carries 62 gallons versus 7 gallons in the Boston Whaler 420 Outrage 2022. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 12 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the Boston Whaler 420 Outrage 2022 and its 600-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Boston Whaler 405 Conquest 2022 with its 300-hp rating is the more economical daily driver.
