3/8 Inch Ratchet and 13/16 Spark Plug Socket
Be careful when loosening or tightening the spark plugs on the Evinrude 150 V6 with the 3/8 Ratchet and 13/16 spark plug socket. Ensure that your socket is straight on the spark plug. If it is cocked to the side there is a good chance you will break the spark plug. I prefer to use a long handled ratchet when removing spark plugs.
