2018 Yamaha F90 Jet Drive - Fits 25 in.
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.
Enhanced Performance and Fuel Efficiency: Multi-point precision fuel injection uses independent fuel injectors to deliver the precise amount of fuel to each cylinder.
Incredible Maneuverability: 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.
- Maximum Overall Performance: Microcomputer Ignition adjusts timing to maintain optimum engine performance, economy and power under all conditions. (F8 and up)
- Ultra-Low Emissions: Yamaha jet drive four strokes are California Air Resources Board (C.A.R.B.) Three-Star Rated for Ultra-Low Emissions and meet all federal EPA requirements.
