Merc 15 HP 1995 spark plug question

[mrking]

I just bought a SELOC service book for to use on my 1995 15HP Merc.<br /><br />It states that the plugs needed for the 15HP is BP8HS-15. I took the plugs out of the motor and they read BP8H-N 10, which are speced to a 20 HP engine.<br /><br />My questions is does my motor have the wrong plugs? Or does it even matter?<br /><br />Thanks everyone.<br /><br />Michael

Hmmm, I wonder why the other ones are in there now?<br /><br />What is the difference between the two spark plug models?
