Scout’s compact dual-console 175 Sport Dorado, rigged with a 90 hp Yamaha four-stroke outboard, jumped on plane and reached 30 mph in 9.2 seconds. Our tester hit a maximum speed of 40 mph at 5,700 rpm twisting a 131/8-by-16-inch Yamaha Reliance stainless-steel three-blade propeller. That’s with two crew members aboard (400 pounds) plus about 14 gallons of fuel. Though powerful and responsive, the Sport Dorado-Yamaha combination sipped that fuel miserly. We noted the most economical and comfortable cruise speed for the 175 Sport Dorado was 29 mph at 4,500 rpm, where we barely ticked over the fuel consumption gauge at 5.2 gph, calculating to nearly 5.6 mpg. Even at full pedal, it achieved 4.4 mpg. At cruise speed, range in this little rig is over 225 miles, leaving 10 percent fuel in the 28-gallon tank for reserve. To put it in what may be more relevant terms, you can fill up on Friday and probably boat right through Sunday without refilling.
