Our test boat was equipped with a pair of 200-horsepower Evinrude E-TEC outboards, which provided plenty of power for the narrow-beamed hull. At a 4,000 rpm cruise, the boat moved along at 38.2 miles per hour with a sound reading of 96 dB-A at the helm. At wide open throttle, or 5,500 rpm, my GPS read 54.3 miles per hour (with a sound level of 102) with three passengers, gear and 95 gallons of fuel onboard in a moderate chop with winds gusting to 15 knots. Factory tests with a single 250-horsepower Evinrude E-TEC outboard produced speeds close to 50 miles per hour. For those who want the peace of mind of twin engines, a pair of 150-horsepower outboards provides both economy and performance.
