Common Question of Honda BF140ALRA
Is BF140ALRA a four-stroke?
Yes. The Honda BF140ALRA is a 140-horsepower four-stroke outboard with remote mechanical controls, electric start, and a 20-inch shaft. Its electronic fuel injection system controls fuel delivery during operation, while the listed configuration provides a high performance outboard motor option for compatible 20-inch-transom boats.
What boats fit its shaft?
A boat with a 20-inch transom is the intended application. Verify the actual transom measurement with the hull manufacturer before installation. Correct shaft length helps maintain cooling-water pickup, gearcase position, propeller immersion, steering control, and cruising efficiency. Accurate measurement supports this ready to bolt marine outboard package.
Does it include electric start?
Yes. The BF140ALRA specification includes electric start and remote mechanical controls. The boat needs compatible battery connections, steering equipment, control-box hardware, and shift and throttle cables. Inspect transom strength and verify every rigging component before installation so the Honda four-stroke powerhead can operate safely and reliably from the helm.
