Honda BF150DJRA 105HP – Jet 20″ Shaft Remote Mechanical

Honda BF150DJRA 105HP Jet Drive 4-Stroke

The Honda BF150DJRA pairs jet propulsion with a 2.4L DOHC VTEC powerhead, delivering 105HP at the jet pump (from a 150HP-class powerhead), built for technical shallow-water navigation in Mulmarine’s marine jet outboards lineup. Its SOHC 16-valve design gives a smooth, quiet ride, and the absence of a lower unit propeller lets boaters traverse areas traditional props can’t reach.

Honda’s Programmed Fuel Injection (PGM-FI) and BLAST technology deliver immediate torque across the 5000-6000 RPM range. The direct 1.00:1 jet drive ratio and a 40-Amp alternator make it a strong choice for aluminum river boats and technical flats skiffs, with Lean Burn Control optimizing fuel consumption and a jet pump built for abrasive, silt-heavy environments.

Advanced Jet Pump Propulsion

The jet pump draws water in and expels it with force to create forward motion, eliminating the propeller and lower unit so the vessel can operate in inches of water without risking damage from rocks, logs, or sandbars.

105HP Jet Drive Performance

While the powerhead is a 150HP-class engine, the jet pump output is factory-rated at 105 horsepower, providing low-end thrust to get heavy river boats on plane in shallow areas where hole-shot acceleration matters.

2.4L DOHC VTEC Powerhead

The 2.4-liter block gives higher torque and smoother power delivery than smaller jet outboards. Honda’s VTEC system optimizes valve lift and timing for both low-speed technical maneuvers and high-speed runs.

Shallow Water Navigation Advantage

Moving the water intake to the bottom of the jet pump lets the engine maintain cooling and thrust in extremely shallow water — essential for river guides and technical flats anglers exploring undeveloped waterways.

BLAST Low Speed Torque

Honda’s BLAST technology advances ignition timing during rapid acceleration to maximize jet pump thrust, cutting the hesitation common in four-stroke outboards for a quicker hole-shot.

NMEA 2000 Networking

This jet drive outboard is NMEA 2000 certified, displaying fuel flow, RPM, and temperature directly on GPS or fishfinder displays.

Japanese Precision Engineering

Every Honda BF150 Jet is built with the precision and quality control associated with Honda’s four-stroke engineering. Pro Tip: regularly inspect the jet pump intake grate for debris or grass to maintain water flow and protect the 2.4L block from overheating in silt-heavy rivers.
