Common Question of Honda BF225DK1UCDA White
Is the white UCDA an iST model?
Yes. The white Honda BF225DK1UCDA retains the iST Intelligent Shift and Throttle configuration and a 30-inch shaft. Its 225-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 transom fits its shaft?
A 30-inch transom is the intended match for this white UCDA model. Verify the actual hull measurement before mounting because incorrect shaft length can affect cooling-water flow, gearcase depth, propeller immersion, steering response, and trim. Correct measurement supports a properly configured ready to bolt marine outboard package.
Does it include electronic shift?
Yes. The iST designation identifies Intelligent Shift and Throttle, which electronically manages compatible gear selection and throttle commands. Confirm the control head, wiring harnesses, gauges, battery requirements, steering components, and rigging procedures before purchase. Proper system integration is essential for smooth and dependable helm operation.
