mercury 4hp 2sroke 2cyl? spark plugs

[volos]

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.
