Boston Whaler 170 Montauk 2013 vs Boston Whaler 255 Conquest 2003 — Same Brand, Different Boat

The Boston Whaler 170 Montauk 2013 vs Boston Whaler 255 Conquest 2003 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 650 hp, the Boston Whaler 255 Conquest 2003 has a 560-hp advantage over the Boston Whaler 170 Montauk 2013's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 13 gal and 15 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Boston Whaler 255 Conquest 2003 is rated for 8 passengers, while the Boston Whaler 170 Montauk 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Boston Whaler 255 Conquest 2003 could be the deciding factor.

Bottom line: Choose the Boston Whaler 255 Conquest 2003 if your priority is putting more people on the water — it handles 8 passengers and at 27,0 ft it has the deck room to back that rating up comfortably. The Boston Whaler 170 Montauk 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

The Boston Whaler 255 Conquest 2003 measures 97" wide, compared to 82" for the Boston Whaler 170 Montauk 2013. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
How do the fuel tanks compare on the Boston Whaler 170 Montauk 2013 and Boston Whaler 255 Conquest 2003?

Yes — both the Boston Whaler 170 Montauk 2013 and the Boston Whaler 255 Conquest 2003 are built by Boston Whaler.
