Honda BF115JK1LRA 115HP – 20″ Shaft Standard Rotation Remote Mechanical

Honda BF115JK1LRA 115HP 4-Stroke Mechanical

The Honda BF115JK1LRA pairs a 2.4L DOHC inline 4-cylinder engine with mechanical control for boaters who prefer traditional cable-driven operation. The 20-inch shaft is built for aluminum fishing boats, mid-sized bay boats, and runabouts in Mulmarine’s 4-stroke marine engine technology 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 BLAST technology deliver 115 horsepower with immediate hole-shot authority. The BF115JK1LRA runs a 2.14:1 gear ratio and a 55-Amp alternator, suited to vessels with high-draw electronics and multi-battery systems, with simplified rigging and mid-range torque.

Massive 2.4L DOHC Architecture

The 2.4-liter block gives higher torque and smoother power delivery than standard 115HP competitors with smaller displacements, reducing mechanical stress and vibration.

Remote Mechanical Steering Versatility

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 mid-sized vessels.

Advanced BLAST Torque System

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

Programmed Fuel Injection (PGM-FI)

The multi-port PGM-FI system delivers the exact fuel and air ratio for current atmospheric conditions, giving turnkey cold starts and crisp throttle response.

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 55-Amp Charging

The 55-Amp alternator (40 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.
