Honda Marine BF40/BF50 EFI Outboards

Features & Exclusives

  • Boosted Low Speed Torque (BLAST) System advances ignition timing during "hammer-down" acceleration, resulting in explosive holeshots
  • Lean Burn Control uses an oxygen (O2) sensor to adjust the air/fuel mixture according to speed and load, providing a 20 percent fuel savings in "cruise mode" from 2500 to 4000 RPM
  • 22-amp Alternator keeps the starting and dual-purpose battery banks charged all day, even when running multiple accessories. The system provides 17 amps of superior battery charging capability
  • Four-Front Corrosion Protection uses a patented, multi-layer paint process and sacrificial anodes to fight corrosion in the harsh marine environment
  • Programmed Electronic Fuel Injection delivers precise amounts of air/fuel to each cylinder, resulting in quick starts, instant throttle response, and low fuel consumption
