Common Question of Honda BF115JLDA
What does BF115JLDA iST mean?
iST means Intelligent Shift and Throttle. This Honda 115-horsepower outboard uses electronic commands for compatible gear selection and throttle operation, reducing dependence on conventional mechanical cables at the engine. Its 20-inch shaft suits matching transoms, while the four-stroke powerhead provides dependable propulsion as a high performance outboard motor.
Does it use fuel injection?
Yes. The BF115JLDA uses an electronic fuel injection system to regulate fuel delivery during starting, acceleration, and cruising. Installation requires compatible iST controls, wiring harnesses, gauges, battery capacity, steering equipment, and proper rigging. Verify every component before installation so the electronic shift and throttle system operates correctly.
What transom height does it fit?
A 20-inch transom is the specified fit for this LDA configuration. Confirm the boat’s actual transom measurement before ordering, since shaft mismatch can affect cooling-water flow, gearcase placement, propeller performance, steering behavior, and engine trim. Correct measurements are essential for this ready to bolt marine outboard installation.
