Miami Boat Show news-Mercury Marine debuted two high-horsepower 4-strokes — the Mercury Verado 350 and the Mercury Racing Verado 400R — and the Mercury Racing 1550 gasoline sterndrive engine.

“We take a bit of pride at Mercury in being about high performance and with these engines we have the fastest, lightest most fuel-efficient, quietest and highest-performing products on the market,” Mercury Marine president John Pfeifer said of the new outboards at a special evening presentation at Sea Isle Marina.

The 350 and 400 become the most powerful recreational outboards ever for the engine maker, now in its 76th year.
