Mercury Verado 400HP CXL Outboard

The CXL badge on this Verado 400 means a 25-inch shaft, with counter rotation checked as an option. It suits boats with a standard-to-tall transom built for this shaft length.

Why shaft length is the first decision

Mercury offers this engine in multiple shaft lengths because transom height varies widely across hull designs; getting this measurement right matters more than any other rigging decision on an outboard this size, more so than picking between finish or rotation options.

Performance and what's included

At full throttle, expect 6200 to 6800 RPM on this engine. Gear changes on this unit run electronically, the steering wheel gets hydraulic assist, vibration-isolating mounts carry over here, and the starter protects against overload. 668 pounds on the scale, this inline-six spins 2.6 liters through 24 valves under dual overhead cams. Counter rotation comes standard on this build, which matters most once a second, opposite-turning engine enters the picture. Tucked into the box are a tool kit, the owner's manual, and mounting hardware. A propeller is not part of what ships here.

How does the CXL compare to the CL? Same engine and electronics, a longer shaft.

Does Mercury back this with a warranty? Yes, for 3 years.

How should I measure for shaft length? From the top of the transom straight down to the keel at the centerline, then compare that to the shaft length offered here.
