Common Question of Mercury 350CXXL
Is the 350CXXL counter rotating?
Yes. The Mercury 350CXXL Verado V10 is specified as a counter-rotation outboard with a 30-inch shaft. Its counter rotating lower unit is intended for compatible paired-engine applications requiring opposite rotation. Confirm engine pairing, propeller specification, controls, steering equipment, battery, wiring, and boat compatibility before installation.
What transom matches its shaft?
A 30-inch transom is the intended match for this CXXL configuration. Measure the hull according to Mercury’s mounting guidance before purchase. Correct shaft depth supports cooling-water pickup, gearcase clearance, propeller immersion, steering response, and balanced twin-engine operation. Accurate measurement supports this ready to bolt marine package.
Does it use fuel injection?
Yes. The Mercury Verado V10 uses an electronic fuel injection system within its applicable powerhead. Verify cooling-water flow, mounting height, propeller requirements, electronic controls, gauges, battery capacity, steering equipment, and complete rigging before installing this high performance outboard motor.
