Hi yal,
I just bought a boat with a '97 Johnson 150 Fast Strike. The spark plugs are BLACK as can be with carbon, I'm thinking that's why it keeps stalling out and running like crap. So I want to change them out but in the owner's manual it says to MAKE SURE you have the appropriate plugs. What are the right plugs to put in this machine.
Thanks,
Davey
