Common Question of Honda BF115JK1XDA White
Is the white iST mechanically different?
No. The white finish changes the exterior appearance, not the listed iST configuration. The BF115JK1XDA White retains Intelligent Shift and Throttle, a 25-inch shaft, and Honda’s 115-horsepower four-stroke architecture with an electronic fuel injection system. Confirm package contents and rigging compatibility before installation on a compatible boat.
Does it include Intelligent Shift?
Yes. This model is identified as an iST outboard, meaning Intelligent Shift and Throttle controls compatible electronic gear selection and throttle commands. The system is designed for smooth helm operation, but it requires matching controls, harnesses, gauges, battery capacity, and installation components. Proper integration allows this high performance outboard motor to operate as intended.
What transom fits its shaft?
A 25-inch transom is the intended match for this model’s extra-long shaft. Measure the boat carefully before purchase and follow the hull manufacturer’s recommendation. Incorrect shaft length can affect cooling-water pickup, gearcase position, propeller efficiency, and handling. Correct measurement supports a properly configured ready to bolt marine installation.
