Honda 115HP iST | BF115JLDA

This new Honda BF115JLDA iST is a 115-hp, four-cylinder outboard built around Honda's Intelligent Shift and Throttle system in place of a standard cable-actuated shift and throttle.

What iST changes

Intelligent Shift and Throttle swaps mechanical cables for electronic control at the helm, which is the main difference between this engine and a standard-throttle 115-hp Honda four-cylinder; check with us whether your existing helm hardware works with iST before ordering, since it calls for matching controls at the console.

Engine specifics

Displacement is 2354cc, this engine reaches up toward 6,000 rpm at full throttle, and fuel delivery is electronic fuel injection. This unit weighs 478 lbs on a 20-inch shaft.

What's included

Honda backs this engine with a 5-year warranty, and the box includes a charging system, a freshwater flush setup, power trim and tilt, and a printed owner's manual alongside the iST-equipped engine itself.

Who picks an iST-equipped engine

Boats already fitted with digital, drive-by-wire controls at the helm are the natural fit for this engine, since iST needs matching electronic hardware rather than the cables and linkage a standard mechanical-throttle Honda uses, so retrofitting an older boat for it is not a simple, straightforward, bolt-on swap.

What does iST stand for? Intelligent Shift and Throttle.

What's the shaft length? 20 inches.

Does it come with a propeller? No, a propeller is not included with this engine.
