F90 Jet Drive

When you need to get to where a prop won’t take you, get an F90 Jet Drive. This 65hp engine is a marine-inspired 4-stroke that’s as much as 50% quieter than a conventional 2-stroke, and up to 30% more fuel efficient, too.

 

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.
