Does the spark plug wiring supposed to match firing order on an outboard motor?
Yes, the spark plug wires on an outboard motor absolutely must match the engine's firing order. Connecting them incorrectly will result in misfires, poor performance, and potential engine damage. The firing order is specific to the engine's design and ensures the cylinders fire in the correct sequence for optimal power and smooth operation. Always refer to your owner's manual for the correct firing order for your specific outboard motor.
