BF 140
Honda’s outboard motors are designed for powerful performance, superior fuel efficiency, and legendary reliability.
Performance and Power:
- VTEC, BLAST, and DOHC: Exclusive VTEC technology balances power, torque, and fuel economy. BLAST improves low-speed acceleration for faster “hole shots.” The 24-valve DOHC configuration boosts high-RPM power.
- Dual Stage Induction: Maximizes air intake for more efficient combustion in the 140 and 150hp models.
- Engine Command Module (ECM): The ECM uses data from 18 sensors to ensure instant starts, smooth operation, strong performance, and excellent fuel efficiency.
Fuel Efficiency:
- Lean Burn Control: This exclusive technology saves fuel, extends your range, and lowers operating costs.
- PGM-FI: Multi-port Programmed Fuel Injection provides easy starts and improved fuel efficiency without sacrificing performance.
Corrosion Resistance:
- Comprehensive Protection: A multi-layered paint process, sacrificial anodes, and stainless steel components provide robust corrosion protection.
- Fresh Water Flushport: Flushes out salt and debris to prevent corrosion.
Reliability:
- Durable Design: Honda’s outboards are known for their durability. Quality improvements include an updated vapor separator, new gasket shapes for better water drainage, and a strengthened starter motor mount.
- True 5 Warranty: The transferable, non-declining warranty is the best in the business.
- Engine Alert System: Monitors vital functions and alerts the operator to prevent engine damage.
Control and Ease of Use:
- iST Control System: The optional Intelligent Shift and Throttle (iST) system provides superb, intuitive control with an ergonomic design and features like automatic tilt, trim support, and cruise control. It also supports multi-engine applications and easy integration with joystick steering.
- Easy Maintenance: Designed for faster, cleaner maintenance with features like a new oil filter position and extended valve adjustment intervals.
- Variable Speed Trolling: A built-in trolling switch allows you to easily adjust your speed in 50 RPM increments.
- Connectivity: NMEA 2000 protocols allow engine data to be displayed on a variety of onboard systems.
Options:
- Colors: Available in white and silver.
- Controls: Choose between the advanced iST system or traditional mechanical controls.
- Models: Counter-rotating models are available for 140hp and 150hp engines.
