8.1 H.O. - 420 hp
The 8.1 H.O. inboard boasts 420 big-boat-moving horsepower. Fitted with our most sophisticated Multiport Injection (MPI) and ignition system, the 8.1 H.O. is the pinnacle of gas inboards. Like all MerCruiser inboards, the 8.1 H.O. is available with a large variety of popular transmissions to fit virtually any application. Digital Throttle & Shift (DTS) is available and is mated to a direct-acting electric shift transmission. DTS eliminates cable maintenance and provides consistent and precise throttle and shift control, and never requires any adjustment. DTS can automatically synchronize multiple engines, provides shift protection and provides SmartStart digital starting. DTS also features Transmission Guardian to automatically protect against damage from overheating or low fluid levels.
