Yellowfin President Wylie Nagler - a former boat racer - likes to go fast, whether it's on the racecourse or in a king mackerel tournament. The 34 delivers here as well. The Verados pushed the big center console to a cruise speed of 40 mph at 4,400 rpm while burning a miserly 23 gph. Push the throttles forward a little more and you've got 45 mph at 4,800 rpm at a 28-gph burn rate. Fast cruise is 50 mph at 5,200 rpm, with a 42-gph burn. Wide open, the 34 hit 56 mph at 6,100 rpm. Want to go faster? Hang triple 275 Verados on the transom, and the 34 reaches a blazing 67 mph.
