Honda BF150DK1XRA 150HP – 25″ Shaft Standard Rotation Remote Mechanical

Honda BF150DK1XRA 150HP 4-Stroke Mechanical

The Honda BF150DK1XRA pairs a 2.4L DOHC inline 4-cylinder engine with mechanical control for boaters who prefer traditional cable-driven helm operation. The 25-inch extra-long shaft is built for aluminum fishing boats, offshore bay boats, and multi-species runabouts in Mulmarine’s 4-stroke marine propulsion lineup that need a familiar tactile feel. The 16-valve DOHC design gives smooth power delivery and reduced vibration.

The PGM-FI system and Honda’s VTEC technology deliver 150 horsepower with immediate hole-shot authority across the 5000-6000 RPM range. The BF150DK1XRA runs a 2.14:1 gear ratio and a 40-Amp alternator, suited to vessels with high-draw electronics and multi-battery systems, with simplified rigging and mid-range torque.

Robust 2.4L I-4 Displacement

The 2.4-liter block gives higher torque and smoother power delivery than standard 150HP competitors with smaller displacements, reducing mechanical stress and vibration.

VTEC Variable Valve Technology

Honda’s VTEC provides a camshaft profile that optimizes valve lift and timing for both low-speed torque and high-speed performance.

Remote Mechanical Control Reliability

This version is built for remote mechanical setups, letting boaters use traditional cable or hydraulic steering — well suited to repower projects with existing steering lines on high-transom vessels.

Boosted Low Speed Torque (BLAST)

Honda’s BLAST technology advances ignition timing during rapid acceleration, cutting the hesitation common in traditional four-stroke outboards for a strong hole-shot.

Lean Burn Control ECOmo

Honda’s ECOmo system adjusts the air-fuel mixture based on real-time speed and load, running a leaner mixture at cruising speed to maximize fuel economy.

High-Output 40-Amp Charging

The 40-Amp alternator (30 Amps charging) supports navigation radar, large multi-function displays, and high-draw livewell pumps without draining the starting battery.

Honda 5-Year Limited Warranty

This engine carries Honda Marine’s 5-year non-declining limited warranty. Pro Tip: use Honda’s genuine 10W-30 marine oil and regular fresh-water flushing to protect the internal 2.4L block.
