Mercury 225CXL FourStroke Cold Fusion DTS

The used Mercury 225CXL FourStroke Cold Fusion DTS is the 25 inch, Digital Throttle and Shift version of this 225 hp V6, finished in Cold Fusion White for a console already wired for digital controls.

Powerhead

This V6 block runs 3.4 liters (209 cubic inches), a 64-degree vee topped with dual overhead cams working 24 valves; bore comes in at 3.6 inches, stroke at 3.4 inches. Full throttle tops out somewhere between 5200 and 6000 rpm.

What to confirm before ordering

Because the control type here is DTS, sold as a separate purchase, a boat still wired for a mechanical cable will need the plain CXL FourStroke instead of this one. Electric start works through SmartStart Protection, and the steering hookup can be hydraulic, power-assist, or joystick piloting, depending on what your console already has in place. Dry weight is 475 lbs. Buyers choosing between the Cold Fusion finish and the plain CXL DTS unit are paying for cosmetics only, since the drivetrain underneath is the same. The propeller is not included, so budget for one sized to your gear ratio and hull.

Repower shoppers moving up from an older carbureted V6 will notice the quieter idle and smoother cruise that EFI and electronic ignition bring, along with less fuss adjusting for altitude or fuel quality changes along the coast.

Most sellers of a used DTS-equipped V6 like this will quote the engine separately from the control head and gauges, so budget for that hardware if your boat does not already carry it from a prior Mercury install.

What finish is this? Cold Fusion White.

Is a propeller included? No, order one separately to match your boat.
