The MerCruiser reputation for unsurpassed performance and reliability extends to our inboards which feature virtually maintenance-free Horizon™ engine technology plus 3 years of factory-backed product protection and 3-year extended maintenance cycle.

But that's only the beginning of the good news. We offer inboards for a wide range of applications in horsepowers ranging from 260 to 420 hp. And now all MPI inboard models come complete with SmartCraft technology which monitors and fine-tunes your engine for peak efficiency and performance through features like our multi-port fuel injection system, Engine Guardian and more. A powerful combination of protection and performance.
