The Fountain 42 Lightning maintains unparalleled performance with just stock horsepower. Staggered engines bring the propellers closer together and keep the center of gravity down low along the keel, where it works best. Preferred power, which is twin 525 EFI Mercury`s, boosts the boat to over 85mph. However, 900 SC`s will easily raise the speedometer well into the triple digits at 110+ MPH.
