The Mercury Marine 240 EFI Jet Drive engine, produced from 2002 onwards, is a powerful and versatile marine powerplant designed for a variety of watercraft applications. It features a 2.4-liter, naturally aspirated, four-cylinder engine with EFI (electronic fuel injection) technology, providing a balance of performance, fuel efficiency, and reliability. The 240 EFI jet drive boasts a maximum output of 240 horsepower, making it suitable for powering everything from personal watercraft like jet boats to smaller fishing vessels and even some light-duty commercial applications.

The engine's jet drive system eliminates the need for a traditional propeller and rudder, offering significant advantages in shallow water operation and maneuverability. The jet drive system uses a pump to create a powerful water jet, which propels the boat forward while also providing excellent directional control. This makes the 240 EFI Jet Drive engine an ideal choice for navigating tight spaces, shallow waters, and even rocky shorelines with ease. The engine's durable construction, including its corrosion-resistant materials and marine-grade components, ensures a long service life and reliable performance in demanding aquatic environments. The 240 EFI Jet Drive engine is a popular choice among boat owners seeking a powerful, reliable, and versatile powerplant for their water adventures.
