Common Question of Honda BF350AXDA White
Is the white AXDA fuel injected?
Yes. The white Honda BF350AXDA uses an electronic fuel injection system and a 350-horsepower four-stroke powerhead. The white finish changes exterior appearance, while the listed configuration retains Intelligent Shift and Throttle and a 25-inch shaft. This makes it a high performance outboard motor for compatible tall-transom boats.
Does it include Intelligent Shift?
Yes. The AXDA White designation identifies an iST model with Intelligent Shift and Throttle. Confirm the control head, harnesses, gauges, battery requirements, steering components, and installation hardware before purchase. Proper electronic integration supports smooth gear selection and throttle response from the helm of this ready to bolt marine outboard.
What transom matches its shaft?
A 25-inch transom is the intended match for this white AXDA model. Confirm the boat’s actual transom height before mounting because incorrect shaft length can affect cooling-water flow, gearcase depth, propeller immersion, steering response, and trim. Follow the manufacturer’s measurement procedure for final fitment.
