Exceptional power & performance
A lightweight powerhouse in a mid-range package; the BF90 offers a host of Honda’s legendary technology, delivering optimum levels of performance whilst ensuring excellent fuel economy.
Features
Boosted Low Speed Torque (BLAST)
Honda’s revolutionary BLAST™ technology provides strong hole shot performance, getting the hull on the plane quicker. This air/fuel ratio and ignition-timing technology boosts engine torque at low RPM under rapid acceleration conditions. It’s NMEA compatible, meaning all engine data including speed, fuel consumption, cruising distance, etc can be displayed on the GPS screen.
NMEA2000 compliance
All Honda outboards from the BF40 to BF250 are NMEA2000 compliant, allowing simplified connectivity with NMEA2000 electronic equipment such as sonars/fish finders, chart plotters and other devices via CANbus network technology.
Variable Valve Timing & Lift Electronic Control (VTEC)
The VTEC™ system, which optimises power and efficiency at all engine speeds, was born out of Honda’s passion for racing. Innovations like these are now available inside many Honda outboards. Developed for high performance engines, VTEC varies the lift and duration of the intake valves to provide optimum performance at both low and high RPMs. VTEC delivers smooth stable idling at low speeds, while increasing valve lift at higher speeds, which broadens the torque curve and top end power.
Programmed Fuel Injection (PGM-FI)
Honda’s renowned Programmed Fuel Injection is controlled by an advanced Engine Control Unit (ECU). Engine sensors precisely control the supply of fuel to the engine, providing easy starting, instantaneous throttle response and superior fuel economy.
Lean Burn Control
Honda’s Lean Burn Control technology, ECOmo, permits combustion to operate on a leaner air/fuel ratio. Sensors precisely measure the air/fuel mixture, ensuring best fuel economy in cruising mode.
Trolling control
Trolling Control is available from BF40 – BF150 & BF200-250 (DBW only). Available on selected Honda outboards, engine speed can be controlled in increments of 50RPM from idle speed to 1000RPM/1100RPM (model dependent). A switch required to activate this feature is available through your authorised Honda Marine dealer as an optional accessory.
