The boat runs 116 mph with Mercury Racing HP 700 SCis and NXT 6 drives, according to Kleitz. He expects it to top 100 mph with the trio of Verado 400R outboards. If you look at power-to-weight ratios, the outboards have the advantage. The Mercury Racing website lists the sterndrive weight at 1,548 pounds each for a total of 3,096 pounds. Divide that by 1,400 hp and you get 2.2 pounds per horsepower. The Verado 400R's weight is 668 pounds. Triple that and you get 2,004 pounds. Divide that by 1,200 and you're down to 1.67 pounds per horsepower. Because of the SL41's 9-foot beam, going with four Verado 400Rs is not an option.
