Honda BF115JLRA 115HP – 20″ Shaft Standard Rotation Remote Mechanical

Honda BF115JLRA 115HP 4-Stroke Mechanical

The Honda BF115JLRA 115HP represents a practical in robust mechanical reliability, featuring a high-displacement 2.4L DOHC inline 4-cylinder architecture for boaters who prefer traditional cable-driven helm control. This 20-inch long shaft model is explicitly designed for aluminum fishing boats, mid-sized bay boats, and runabouts requiring dependable 4-stroke marine engine technology with a familiar tactile feel at the helm. Its 16-valve DOHC design helps support smooth power delivery and reduced vibration, providing a refined operating experience that 4-stroke boaters have come to expect from Honda’s legendary Japanese craftsmanship.

Operational peak performance is managed through the PGM-FI system and Honda’s BLAST technology, ensuring that 115 horsepower is delivered with immediate hole-shot authority across a competitive 4500-6000 RPM range. The BF115JLRA features a specialized 2.14:1 gear ratio and a high-output 55-amp alternator, making it the ideal choice for vessels with high-draw electronics and multi-battery systems. US boaters consistently choose this mechanical Silver series model for its simplified rigging, mid-range torque, and the durability of its wet sump lubrication system for long-term reliability in both fresh and saltwater environments.

2.4L DOHC Displacement

The BF115JLRA utilizes a large 2.4-liter block to provide significantly higher torque and smoother power delivery than standard 115HP competitors with smaller displacements. This balanced architecture reduces mechanical stress and vibration throughout the vessel while providing the torque needed for rapid response under heavy loads. Operators may notice a refined four-stroke quietness with the mid-range pulling power essential for navigating unpredictable coastal inlets or large lake environments.

Remote Mechanical Control Reliability

This version of the 115HP Honda is designed for remote mechanical setups, allowing boaters to utilize traditional cable or external hydraulic steering systems for a familiar tactile feel at the helm. This configuration is ideal for repowering projects where existing steering lines and mechanical throttle controls are already in place on mid-sized vessels. Owners gain the advantage of next-generation 4-stroke power and efficiency while maintaining their preferred mechanical interface for technical navigation.

Advanced BLAST Torque System

Honda’s Boosted Low Speed Torque (BLAST) technology proactively advances ignition timing during rapid acceleration to get the boat on plane faster. This system eliminates the “dead zone” often found in traditional 4-stroke outboards, providing a hole-shot that rivals many 2-stroke competitors in the 115HP class. Captains gain improved vessel authority, allowing them to carry heavier loads or pull skiers with the confidence of immediate, high-torque thrust from a dead stop even on heavier fiberglass hulls.

Programmed Fuel Injection (PGM-FI)

The BF115 utilizes a multi-port PGM-FI system that uses a series of sensors to deliver the exact amount of fuel and air required for current atmospheric conditions. This helps support instant, turnkey starts in cold weather and crisp throttle response throughout the entire power band from idle to wide-open throttle. US This can provide the advantage of high-pressure fuel efficiency and reduced emissions, making it one of the most eco-friendly and cost-effective outboards for long-distance cruising.

Lean Burn Control ECOmo

Honda’s ECOmo system utilizes a sophisticated lean-burn technology that adjusts the air-fuel mixture based on real-time speed and load for maximum efficiency. At cruising speeds, the engine operates on a leaner mixture to maximize fuel economy without sacrificing smooth operation or mechanical power. This results in best-in-class fuel efficiency, allowing owners to stay on the water longer and reduce their total cost of ownership at the fuel dock throughout the season.

High-Output 55-Amp Charging

The BF115JLRA features a powerful 55-amp alternator (40 amps charging) that provides the highest electrical output in its class to keep all onboard electronics fully powered. This capacity easily supports modern navigation radar, large multi-function displays, and high-draw livewell pumps without draining the primary starting battery. Owners gain the confidence to run complex digital networks throughout the day, ensuring all critical safety and fish-finding gear remains operational.

Honda 5-Year Limited Warranty

Your investment is protected by Honda Marine’s high-pressure 5-year non-declining limited warranty, which remains consistent from the first day to the last. This warranty reflects the confidence Honda has in their Japanese-engineered components and provides US boaters with peace of mind during every launch.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
