F40 Jet Drive

When you need to go places no prop could, the 30-hp F40 Jet Drive is the perfect choice. Packed with power, it’s also compact, quiet, lightweight and efficient.

 

Multi-point precision fuel injection uses independent fuel injectors to deliver the precise amount of fuel to each cylinder.

 

With no gearcase or propeller extending below the hull, a jet drive allows you to manoeuvre around or pass over obstructions that would limit the travel of a conventional, propped outboard.
