The Bayliner 180 OB 2010 tops out at 125 hp. Engine specs for the Bayliner 175 2005 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 21 gal and 23 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Bayliner 180 OB 2010 is rated for 7 passengers, while the Bayliner 175 2005 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 180 OB 2010 could be the deciding factor.
