Named one of Boating Industry's Top Products and proven to withstand both extreme torque and speed/power conditions, this is a nicely balanced recreational sterndrive engine that fills the power void currently experienced in the gasoline sterndrive segment between recreational duty 430 HP and high performance 520 HP+.
Uniquely positioned at 483 HP, the 7.4L MPI-S meets a long-awaited need for manufacturers as well as boating enthusiasts, providing substantial power and torque for sportier cruisers and bowriders without sacrificing Ilmor's renowned durability that owners have come to depend upon for trouble-free boating.
The 7.4L MPI-S engine is hand-built in Ilmor's Plymouth, Michigan racing headquarters, with Ilmor-designed internal components, including a forged crank, rods, and pistons. The engine comes standard with closed-cooling and electric throttle, and also features a performance-tuned cast aluminum intake and easily accessible service points.
