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

I've done that before G. Ouch. The testers were cheaper online and it'll be next weekend before I can fool with it . Got the plugs coming also . $5.25 each
