Just making sure I ain't screwing up and buying the wrong ones. I just ordered a Compression tester and a Spark tester to start narrowing things down on the motor so I can get back to feshing. I did a search and found that the NGK BP8H-N-10 seems to be the right plugs. This was from the Mercury wensite. Is NGK a good brand? Before you ask, NO, I ain't at the house to check what's in it now. LOL
NGK = no good kind rotfl i think most jap motors run them
Good plugs.
If wait on the compression tester. If u have low compression, u won't need new plugs and u can use the $ u save for the new motor. Your welcome.
Speaking of motors. You ever get everything back up and running?
NGKs are what you need to be running and that's a pretty standard Merc plug number so its most likely what you need. Why didn't you just get a compression tester at the parts house??? It will be more accurate if you crank the motor, if it will and let it warm up a little bit.
NGK are good plugs

That's why I surprised to find em at Oreillys for that price, oh well you will know for next time, prolly aint but 4 of em anyway.
You could just get Cray to hold the end of the plug wire while you hit the starter....if you hear cussing it works....if you don't hear cussing your not getting fire :Rofl
:Rofl:Rofl:RoflThis may result in false results cause there will be cussing fire or no fire!!!!!!!!!:Rofl:Rofl:Rofl:Rofl:RoflQuote:

Oh yeah, the -10 on the end of the plug number means it's pre gapped. Still might check the gap tho.
Gotta check with Oreillys for some BPZ8HS-10.
Thanks. Didn't kniw hat

Don't know what the pre set gap is, that's why I said to check them with the engines recommended gap.Quote:

ALWAYS replace your plugs with the recommended Brand. No cross referenced brand should be used.
I thought Merc recommended Champion, but that could be Johnson/Evinrude that does.
You guys rough on a old guy:Rofl:RoflQuote:
