FOUR STROKE TUNNEL RACE

The 60 h.p. in-line four-cylinder 60 EFI FormulaRace outboard expands Racing’s breadth of low-emissions 4-strokes; an offspring of the venerable Verado 400R and 400 ROS  outboards. The engine, built at Mercury Marine’s state-of-the-art outboard manufacturing facility in Suzhou, China, was designed specifically to meet increasing demand for engines in support of the popular Mercury FormulaFour outboard tunnel boat racing series.
