Honda 150HP iST | BF150DXDA

The BF150DXDA is Honda's standard-rotation 150 hp iST outboard built on a 25-inch shaft, the non-counter-rotating option among the iST engines Honda offers at this power.

iST and shaft fit

This engine swaps the usual mechanical shift-and-throttle cable for an electronic iST link, so confirm your helm wiring matches that setup before you order. This model's shaft measures 25 inches; check your transom height carefully, since the wrong mounting height changes how deep the propeller sits once the boat is loaded. A four-cylinder, 2354cc design runs on EFI and starts electrically, with no manual backup starter fitted to this engine. Rigging it is the same job as any other iST-equipped Honda outboard in this size range.

Running range and weight

Weighing 478 lbs, this motor's full-throttle window falls between 5000 and 6000 rpm according to Honda's published figures. Buyers cross-shopping this against the counter-rotating version should note the rotation difference is the whole story; everything else about the two, from shaft length to the iST controls, carries over unchanged between them.

Common questions

Is this the counter-rotating version? No, Honda sells that as a separate model; this one turns the standard direction.

What's standard? A charging system, a fresh water flush fitting, power trim and tilt, an owner's manual, and a 5-year warranty; a propeller is not included with this engine.
