I have a 4hp mercury 2stroke (2 cylinders?) outboard engine with SN 9213229.<br />Can you tell me what kind of spark plugs can I use for this?<br />I'm a little confused 'cause I bought this by second hand and I'm not sure if the inside of the engine is what it's written on cover.
Does anyone know what kind of spark plugs can I use for a mercury 4hp 2stroke 2cylinder engine?<br />The manufacture date must be around 1990, it has the airchoke at right, the hand starter and the trasmission switch at left.Best regards
