Common Question of Honda BF140AXRA
Is BF140AXRA a four-stroke?
Yes. The Honda BF140AXRA is a 140-horsepower four-stroke outboard with remote mechanical controls, electric start, and a 25-inch shaft. Its electronic fuel injection system controls fuel delivery across operating conditions, while the configuration provides a high performance outboard motor option for compatible tall-transom boats.
What transom fits its shaft?
A 25-inch transom is the intended fit. Measure the boat before purchase and follow the hull manufacturer’s shaft recommendation. Correct positioning helps maintain cooling-water pickup, gearcase depth, propeller immersion, steering response, and efficient trim. Accurate measurement supports installation of this ready to bolt marine outboard package.
Does it include remote controls?
Yes. Remote mechanical controls and electric start are listed for the BF140AXRA. The installation requires compatible shift and throttle cables, control-box hardware, steering equipment, battery connections, and suitable transom reinforcement. Verify cable travel and component compatibility before operating the Honda four-stroke powerhead from the helm.
