Honda BF115JK1XDA 115HP Outboard – 25in Shaft, iST

Fit the Honda BF115JK1XDA 115HP Outboard to a digital-ready boat that requires a 25-inch X-long shaft and electronically managed controls. Its 2,354 cc inline four-cylinder DOHC engine uses 16 valves and produces 115 HP at 5,250 RPM for properly rated center consoles and other recreational hulls. Honda BF115JK1XDA is an iST drive-by-wire outboard with Programmed Fuel Injection, electric starting, and Power Trim & Tilt. The X-long configuration gives this model a different installation requirement from the 20-inch version.

The 485-lb dry weight should be considered before a repower, especially when the previous motor was lighter. Engine output is specified across a 4,500–6,000 RPM full-throttle range, giving owners a reference for propeller and hull setup. The 40-amp alternator provides 30 charging amps for supported equipment. The listed oil capacity is 6.7 L with filter, while gearcase lubricant specifications and service intervals require confirmation from the applicable Honda documentation.
