Good plugs
Spark plugs work great but shipping is very slow

Not in OEM packaging
These are the correct plugs for my 9.9 Yamaha Outboard. Only thing is they didn't come in boxes as pictured with the protective cardboard rings to protect the gap spread. You'll have to check it. Not a big deal.

Plugging the spark
Bought it, gapped it, slapped it in a 1986 Mariner 15hp CDI Marathon outboard motor and went to lake. Runs like a top (it's the OEM plug for this outboard). The plug sealed better then the Autolite plugs and ran better then the Champion plugs.If you have the same motor the gap is 38, if you have the non-marathon version it's 32, if you have a non-CDI version of the same motor.. you need a B7HS plug not the "-10" version. Although I have read somewhere, that the plugs are the same - the only difference in the gap from the factory (who trusts factory gapping anyways?).So there you go, it's a spark plug and it sparks.
