Common Question of Honda BF350AUCDA White
Is the white UCDA an iST model?
Yes. The white Honda BF350AUCDA retains the iST Intelligent Shift and Throttle configuration and a 30-inch shaft. Its 350-horsepower four-stroke powerhead uses an electronic fuel injection system. The white finish identifies exterior appearance, while compatible rigging is required for this high performance outboard motor installation.
What shaft length does it use?
The shaft length is 30 inches, intended for a matching tall transom. Confirm the boat’s actual measurement before mounting because incorrect shaft length can affect cooling-water flow, gearcase depth, propeller immersion, steering response, and trim. Proper measurements support this ready to bolt marine installation.
Does it include Intelligent Shift?
Yes. The UCDA White designation identifies Intelligent Shift and Throttle, which electronically manages compatible gear selection and throttle commands. Confirm the control head, wiring harnesses, gauges, battery capacity, steering components, and installation requirements before purchase. Proper integration supports smooth and dependable helm operation.
