Honda 225HP iST | BF225DUDA WT

The BF225DUDA WT is a 225-horsepower four-stroke built around Honda's electronic iST shift-and-throttle system, giving smoother gear engagement and steadier throttle feel than a mechanical cable. Confirm shaft length, mounting weight, and cylinder count with us directly before ordering.

Technology under the cowling

Alongside iST, Honda pairs this engine with BLAST for a short burst of extra fuel on acceleration and VTEC for a broader usable power band, plus multi-port programmed fuel injection to meter delivery across the throttle range. Honda also calls out corrosion resistance built for running in fresh and saltwater alike on this motor, useful for owners who split time between the two.

What to verify before buying

Measure your transom and talk to us about fitment rather than assuming this matches another 225-horsepower Honda by name alone, and make sure your helm is wired for electronic iST control rather than a mechanical steering cable, since that hardware is not interchangeable with a cable-actuated setup.

Common questions

Does this share the same iST hardware as other 225-horsepower Hondas? Yes, electronic shift-and-throttle control is part of this engine too.

What other technology is built in? BLAST and VTEC for throttle response and power band, plus programmed fuel injection and added corrosion resistance.

Is this motor suited to saltwater use? Honda builds the corrosion resistance on this engine for both fresh and saltwater running.
