Thrilling Video: Take a Ride with Seven Marine's 557 hp Outboards | Sport Fishing

..."When equipped with two or more 557 outboards and a bow-thruster, a boat can also employ a joystick-control system to help ease low-speed maneuvering in tight quarters. While the outboards do not turn independently, the electronic shifting and bow-thruster work in unison to let you pivot and walk the boat into a slip.

At speed, integral power-assist hydraulic steering developed in partnership with Latham Marine helps rein in the big outboards. Listed at 1,045 pounds, the 557 weighs 282 pounds more than the next heaviest outboard, Yamaha’s 763-pound F350 V-8. The 557’s power-to-weight ratio is 0.53 – 15 percent greater than that of the Yamaha F350, about the same as Mercury Racing’s Verado 350 SCi and 7 percent lower than Evinrude’s E-TEC 300. "
