Honda 225HP iST | BF225DUDA

A 30-inch shaft carries the BF225DUDA's 225-horsepower four-stroke V6 powerhead. 628 lbs is the figure Honda lists for this configuration. This motor uses electronic iST control for shift and throttle instead of a mechanical cable. Electric starting comes standard, and the gearcase spins the conventional direction Honda uses across most single-engine installs. Six cylinders and EFI fuel injection make up this 3583cc block.

What to confirm before buying

Your transom height should match this 30-inch shaft; confirm it before ordering rather than assuming from the boat's overall size. Full-throttle operation on this block falls within 5000-6000 rpm. Unlike the DUCDA in the same family, this version skips counter-rotation entirely. Most buyers here are swapping out an older motor rather than rigging a boat for the first time.

Equipment list

Beyond the digital shift-and-throttle hardware, this unit includes charging capacity for your electronics, a point for flushing the cooling passages, and trim and tilt; wrapping up with the manual and Honda's 5-year protection. Propellers for this engine are sold apart from the motor.

Will this work on a single-outboard boat? Yes, standard rotation is exactly what a single-engine installation calls for.

Could this motor be paired with a second engine later? Only as the standard-rotation side, matched against a counter-rotating DUCDA on the opposite transom.

What starting system does this engine use? Electric start is standard on this configuration.
