5.7 Horizon DTS: Dependable, Efficient & Clean, Fluidly Smooth, Digitally Precise, Unmatched Reliability

Smooth Cruising

If frequent stops for service and repairs aren't something you look forward to, it's time to consider Mercury MerCruiser's inboard line. Ranging from 300 hp to 425 hp, these capable v-8 inboards are designed to combine high performance with reliability - ensuring that you get to your destination quickly and return home again safely. Their durable design, tested over thousands of sea miles, makes them virtually maintenance-free.

Power & Performance

High-displacement volume and premium MPI fuel injection combine to deliver outstanding acceleration, instant planing and smooth performance throughout the rpm band. Mercury SmartCraft Digital Throttle & Shift is standard, providing precision throttle response and effortless steering.

Corrosion Protection

The freshwater closed-cooling system (standard) dramatically limits potential corrosion. In fact, Mercury is so bullish about the anti-corrosion technology built into these engines, we offer a standard three-year limited corrosion warranty.

Durable & Reliable

Rugged durability is ensured by high technology and heavy-duty componentry. Mercury’s Engine Guardian monitors critical sensors for any sign of a problem and immediately takes action to stop engine damage. You’ll enjoy hours of hassle-free operation thanks to standards like the water-cooled Cool Fuel delivery system, which prevents vapour lock.


Electronic MPI and standard ECT combine to deliver precisely the correct amount of fuel for every stage of operation – no more, no less. The result is fuel economy that stretches your boat’s range and your dollar.
