I have a 97 Merc 115HP 2 stroke outboard.

Just doing a tuneup on it and it had Autolite 4092 in it. I called the local boat shop and they said that engine takes a NGK BP8H-N-10

Does this sound right to you? Or is there a better plug for this engine?

Also what would the plug gap need to be set at?


Thanks guys!

NGK BP8H-N-10 is the right plug. The gap is .040
