The Mercury Mariner 240 HP EFI Jet Drive, produced from 2001 to 2008, is a powerful and versatile outboard engine designed specifically for shallow water applications. This engine utilizes Mercury's innovative Jet Drive system, which replaces the traditional propeller with a water jet propulsion system.

This makes it an ideal choice for recreational boating activities, fishing, and even light-duty work on waterways with limited depth.

The Mariner 240 is powered by Mercury's 2.5L 4-cylinder engine, which boasts a fuel-injected electronic fuel injection (EFI) system for smooth and efficient performance. The EFI system delivers precise fuel-air mixture control, resulting in increased fuel efficiency and reduced emissions. The engine is also equipped with a robust and reliable starting system, ensuring effortless ignition in all conditions. The Mariner 240's Jet Drive system delivers exceptional maneuverability and control, allowing for precise handling in tight spaces and swift acceleration. The system's ability to operate in shallow water opens up a wide range of boating opportunities, making the Mariner 240 a perfect choice for exploring lakes, rivers, and coastal areas.
