Honda BF90D5XRTA 90HP – 25″ Shaft Standard Rotation Remote Mechanical

Honda BF90D5XRTA 90HP SOHC VTEC

The Honda BF90D5XRTA is a versatile 90HP Four Stroke outboard engineered for remote steering performance on high-transom vessels in the US recreational market. Featuring a generous 1.5L inline four-cylinder displacement and weighing 379 lbs, this motor delivers a superior power-to-weight ratio for sustained coastal cruising. The 25-inch extra-long shaft length is perfectly calibrated for offshore walkarounds, deep-V center consoles, and large pontoon hulls. Our reliable marine outboard engines provide the mechanical simplicity necessary for dependable everyday maritime operation.

Maximum operational performance for this Honda 90HP is achieved across the 5300 to 6300 RPM full throttle range. The robust 2.33:1 gear ratio helps support the engine translates its torque curve into immediate hole-shot acceleration and steady hull planing. Constructed with Japanese engineering, this corrosion-resistant unit features advanced vibration dampening to helps support a quiet, comfortable ride during marine salt-water excursions in the American coastal environment.

VTEC Performance Engineering

The inline four-cylinder VTEC platform maximizes thermal efficiency while maintaining structural rigidity. This proven design delivers the smooth, reliable torque required to push heavily loaded center consoles and pontoons through strong tidal currents and unpredictable offshore chop.

PGM-FI Induction Efficiency

By continuously monitoring engine parameters, the PGM-FI system delivers the appropriate fuel mixture. This precise fuel induction helps support instant throttle response and prevents stalling when navigating through treacherous coastal inlets or executing tight harbor maneuvers.

Extra-Long 25-Inch Propulsion

The 25-inch extra-long shaft helps support the propeller operates at the optimal depth for maximum hydrodynamic grip on high transoms. This design prevents cavitation and maintains consistent forward thrust on mid-sized deep-V hulls navigating through rough coastal bay waters.

High-Capacity 44A Alternator

With a belt-driven 44 Amp alternator, this engine generates 35 Amps of net charging power. This robust electrical output keeps multiple battery banks charged, ensuring high-draw electronics, livewell pumps, and entertainment systems remain flawlessly operational.

Comprehensive Factory Warranty

Honda Marine protects this 90HP outboard with a comprehensive five-year limited warranty for US owners. This factory-backed coverage helps support access to genuine replacement parts and certified technicians, reflecting a deep commitment to long-term maritime reliability and performance.

High-Transom Pontoon Match

This remote mechanical outboard is a practical power solution for large pontoon boats and fiberglass walkarounds. It provides the sustained high-end thrust needed for navigating difficult coastal tidal flows while remaining fuel efficient during operation.

Maintenance & Longevity

Maintaining clean oil in the wet sump lubrication system is vital for preserving tight engine tolerances over time. Always flush the cooling system with fresh water after every saltwater outing to maintain internal corrosion-resistant properties.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
