Mercury Mercruiser Engines

Multiport Fuel Injection 5.0 MPI - 260 hp

The 5.0 MPI is one of our most popular engine choices. With 260 hp, it provides excellent power for tow sports, larger runabouts and cruisers. Its proven V-8 base engine delivers year-after-year performance and reliability. All our V8 Bravo Multi-Port Injection (MPI) sterndrive models are available with optional Digital Throttle & Shift (DTS). DTS eliminates cable maintenance and provides consistent silky-smooth shifting.
