Mercury 250HP XXL FourStroke Outboard DTS

This Mercury 250HP XXL pairs the longest shaft in the line with digital throttle and shift, for the tallest standard transoms here that also have a helm wired for Mercury's electronic controls rather than cables.

Long shaft, electronic helm

Confirm your transom height matches before ordering a shaft this long. DTS requires compatible digital helm hardware, so check your existing rigging or new-build plan before choosing this over a cable-steered version.

Rotation and inclusions

Counter-rotation availability is not part of this listing. Hardware for mounting, a tool kit, and the printed manual all ship standard. You will source a propeller separately, since it isn't bundled.

Q: Is this different from a cable-steered XXL? Only in steering and shift. This V-8 tips the scale at 527 lbs dry. This V-8's displacement is rated 4.6. This V-8 tops out at 5200 to 6000 RPM.

Trim and tilt are powered, and fueling is EFI, both standard. This new motor is backed for 3 years by Mercury Marine. Double-check your boat manufacturer's recommended transom height before ordering any shaft length. Manufacturers often publish this figure in the owner's documentation. Control type and shaft length are worth confirming together, since changing one sometimes affects the other. A rigger familiar with your hull can flag fitment issues early, before anything ships.

The long shaft and the electronic helm are the two details that define this particular build. Confirm your boat's existing gauge package is compatible with digital throttle and shift before the engine arrives.
