Mercury's new 3.4-liter V-6 FourStrokes include 175, 200 and 225 hp models that showcase innovative design changes as well as convenience features. The three new engines extend the company's current FourStroke lineup, and replace the four-cylinder Verados and the six-cylinder 225 hp Verado. At 475 pounds for the 20-inch versions, these outboards are light and compact, thanks to refinements such as nesting the alternator in the notch of the V-shaped cylinder banks. Mercury also designed a small hatch in the cowling that pops open to reveal an engine-oil dip stick and fill port. All three outboards are available with 20- or 25-inch shaft lengths; the 225 also comes in a 30-inch model. Prices start at $16,225 for the 175; $17,175 for the 200; and $18,620 for the 225.
