Common Question of Mercury 400CL White
Is the white 400CL counter rotating?
Yes. The white Mercury 400CL Verado V10 is specified as a counter-rotation outboard with a 20-inch shaft. Its counter rotating lower unit supports compatible paired-engine applications. The white finish identifies appearance, while propeller, controls, steering, battery, wiring, fuel system, and boat compatibility must be verified before installation.
Does it use fuel injection?
Yes. The white 400CL Verado V10 uses an electronic fuel injection system within its applicable powerhead. Counter rotation describes the propulsion configuration. Verify engine pairing, propeller specification, cooling-water flow, mounting height, Verado controls, gauges, battery capacity, and steering equipment before installing this high performance outboard motor.
What shaft length does it use?
The shaft length is 20 inches, intended for a matching transom. Measure the boat according to Mercury’s mounting guidance before purchase because incorrect shaft depth can affect cooling-water pickup, gearcase clearance, propeller immersion, steering response, and balanced twin-engine operation.
