The Honda BF90D5LRTA represents Honda’s mid-range outboard engineering excellence, delivering robust 90 horsepower through a sophisticated 1.5-liter SOHC 16-valve engine inspired by Honda’s proven HR-V automobile technology. The 20″ long shaft configuration makes this outboard ideal for a wide range of vessels including bass boats, bay 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 mechanical controls offer reliable, direct response that many boaters prefer, delivering precise boat handling through proven cable-actuated throttle and shift mechanisms. The power trim and tilt system provides convenient adjustment capabilities for optimal performance across varying speeds and load conditions.
Built upon Honda’s renowned automotive engineering foundation, the BF90D5LRTA features Honda’s exclusive VTEC® technology that synchronizes the lift and duration of intake valves at both low and high RPM, yielding a longer, flatter torque curve for maximum power at every speed. 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 the 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 while meeting stringent emission standards. The robust 44-amp alternator provides reliable charging power, delivering 35 amps of charging power to keep onboard electronics operational.
The 3-way cooling system ensures optimum operation and long-term durability by maintaining even temperatures across all cylinders, while cast iron cylinder sleeves ensure long-term durability. The high-performance gearcase reduces drag, eliminates hull porpoise, and minimizes spray for increased acceleration and top speed, making it the lightest in its class at just 359 pounds.
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 variable speed trolling control with push-button operation in 50 RPM increments, 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 bass boats, bay boats, and center consoles requiring 20″ shaft length with traditional mechanical controls and power trim/tilt, the Honda BF90D5LRTA combines proven 4-cylinder reliability with VTEC® performance and mechanical steering precision, delivering the dependable performance that experienced boaters demand for their marine adventures where traditional control reliability and proven operation are valued.
