Honda 115HP iST | BF115JXDA

Honda's BF115JXDA delivers 115 hp from the same iST-controlled four-stroke platform as its siblings, but on a longer 25-inch shaft and in Honda's standard finish rather than the white-cowling option.

Fit before you buy

This shaft measures 25 inches, so check your transom height carefully before ordering; getting the mounting height wrong changes how the propeller tracks once the boat is loaded and underway at speed. Four cylinders add up to 2354cc here, EFI handles fuel delivery, and an electric starter does the starting rather than a pull cord at the cowling. Shift and throttle route through iST's electronic control rather than a mechanical cable on this motor, so check that your helm's control head matches that interface before you buy cable hardware for it.

Running range and what's included

Honda's full-throttle band for this engine runs 4500-6000 rpm. This configuration ships with power trim and tilt, a built-in charging system for the battery, a fitting to flush the cooling system with fresh water, and an owner's manual, but it does not come with a propeller; plan to add one sized to your boat separately before your first outing. At 485 lbs, it carries Honda's 5-year warranty on the powerhead and its components.

Common questions

Does this come with a propeller? No, that is purchased separately.

What shaft length is this model? 25 inches, meant for a taller transom than the shorter version Honda also builds.
