115 HP four-stroke, 2,354cc 4-cylinder DOHC
25″ extra-long shaft, iST drive-by-wire
BLAST™, Lean Burn, 40-amp charging
Power trim/tilt, NMEA 2000 compliance
The Honda BF115JXDA is a high-performance four-stroke outboard motor designed for medium to large boats, such as pontoons, center consoles, multi-hulls, and bay boats up to 18-22 feet. Featuring a 25-inch extra-long shaft, it weighs 493 lbs and is powered by a 2,354cc (143.6 cubic inch) four-cylinder DOHC engine with 16 valves, delivering 115 HP at 5,250 RPM (4,500-6,000 RPM range). Equipped with Honda’s Intelligent Shift and Throttle (iST) drive-by-wire system, electric start, and power trim/tilt, it offers precise control and easy installation. The motor incorporates Honda’s BLAST™ (Boosted Low Speed Torque) for enhanced hole shots, Lean Burn Control for superior fuel efficiency, and a 3-way cooling system for thermal management. Built for durability in freshwater and saltwater, it features a multi-layered corrosion protection system with sacrificial anodes, waterproof connectors, and a stainless steel exhaust. The redesigned cowl, water separator, fuel filters, and enlarged dipstick tube reduce maintenance time, while NMEA 2000 compliance ensures integration with onboard electronics.

5 reviews for Honda 115hp 25″ Shaft | BF115JXDA
this Honda 115 is a beast — smooth, responsive, and plenty of torque even under load. the 25″ shaft works great. I’m really impressed with how quiet it runs.
very reliable and good performance. a bit heavier than expected when mounting, but once on the water — smooth and consistent.
runs beautifully. the mid‑range power is strong, and it handles rough water confidently. love that it doesn’t overheat even on long runs. very pleased.
fantastic upgrade. this engine pulls hard yet feels refined. got it at a surprisingly good price — for what you get, it’s a steal. highly recommend.
great motor overall. starts easily and gives a steady performance. I docked one star because the rigging a bit fiddly at first but once set up — solid.
