Honda BF115JXRA 115HP in White 25″ Shaft Standard Rotation Remote Mechanical

Honda BF115JXRA 115HP 4-Stroke VTEC White

The Honda BF115JXRA pairs a 2.4L inline 4-cylinder engine with VTEC technology, finished in Grand Prix White. The 25-inch extra-long shaft is built for high-transom bay boats and offshore skiffs in Mulmarine’s 4-stroke marine engines 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 a “best of both worlds” power curve across a 4500-6000 RPM range. The BF115JXRA runs a 2.14:1 gear ratio and a 55-Amp alternator, suited to offshore vessels with high-draw electronics and multi-battery systems, with simplified mechanical rigging.

Grand Prix White Custom Aesthetic

The Grand Prix White finish matches modern fiberglass and aluminum hulls, engineered to withstand saltwater environments and UV exposure.

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.

Extra-Long 25-Inch Shaft Propulsion

Calibrated for 25-inch transom heights, this shaft keeps the lower unit deep enough to prevent ventilation in heavy following seas.

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.

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.
