The Honda BF40D4LRTA represents Honda’s refined mid-range outboard engineering, delivering robust 40 horsepower through a sophisticated 3-cylinder SOHC 6-valve engine designed for diverse marine applications. The 20″ long shaft configuration makes this outboard ideal for a wide range of vessels including aluminum boats, inflatables, flats boats, and center consoles with standard transom heights, providing optimal propeller positioning for enhanced performance and efficiency.
This mechanical steering model features Honda’s smooth-operating traditional command and control system, providing experienced boaters with direct mechanical linkage that’s compatible with most repower applications and existing steering systems. The power trim and tilt system provides convenient adjustment capabilities for optimal performance across varying speeds and load conditions, while the 2.08:1 gear ratio delivers balanced performance for general boating applications.
Built upon Honda’s proven marine engineering foundation, the BF40D4LRTA features Honda’s advanced PGM-FI fuel injection system, delivering precise fuel and air mixture to each cylinder for easy starts, instant throttle response, and superior fuel efficiency. The innovative BLAST™ technology aggressively advances ignition timing for dramatically improved hole shots and acceleration, while Lean Burn Control technology delivers exceptional fuel efficiency by optimizing the air-fuel mixture during cruising speeds, running 20% more efficiently than competitive engines in its class.
Honda’s legendary reliability shines through with consistent performance and dependable operation, ensuring optimal fuel delivery in all conditions while meeting stringent emission standards. The robust 22-amp alternator provides superior charging power, delivering 17 amps of charging power to keep onboard electronics operational – significantly more than competitive models in this class.
The high-performance gearcase is designed to reduce drag, eliminate hull porpoising, and minimize spray, resulting in increased acceleration and top speed. At just 214 pounds, the BF40D4LRTA is among the lightest engines available in its class, making it perfect for aluminum boats, inflatables, and flats boats where weight and performance are important considerations.
The classic Aquamarine Silver finish provides excellent corrosion resistance while maintaining Honda’s distinctive marine aesthetic that has defined quality marine propulsion for decades. Standard features include NMEA 2000® certification for seamless electronics integration, built-in speedometer pickup, freshwater flush port, and Honda’s comprehensive corrosion protection system featuring multiple anodes and specialized marine coatings designed to withstand harsh saltwater environments.
Perfect for aluminum boats, inflatables, flats boats, and center consoles requiring 20″ shaft length with traditional mechanical controls and power trim/tilt, the BF40D4LRTA combines proven 3-cylinder reliability with advanced fuel injection technology and mechanical steering precision, delivering the versatile performance that recreational boaters demand for their marine adventures where lightweight design, traditional control reliability, and proven operation are valued.
