"The plugs recommended are hard to find (Champ J4J, AC-M42K,and Auto-Lite A21X). Anyone using a more commonly found plug?
Thanks Mark"
 
J4C would be the equivalent to

J4C would be the equivalent to J4J. My guide from OMC now states for J6C plugs to be used. I suspect that if you are doing a lot of trolling then the J6C would be a better choice. If you are usually running it full out the J4C would be fine. The 6 plugs are a little hotter than the 4s.

I never use a torque wrench for spark plugs. Just snug them finger tight and then about 1/4 turn more for used plugs and maybe a little more (closer to a 1/2 turn) for brand new plugs.
 
"You will notice a new plug ha

"You will notice a new plug has to squish the washer. After that it will tighten right away. Make sure the electrode is centered under the reach and gap at .025 or so. I use anti seize on all plugs too and lube boot with some dielectric grease. I recommend Amsoil fully syn 100:1 oil but mix @ 64:1 or 12 oz to 6 gallons non oxy fuel. Your new plugs will last until your coils crack or points go bad, ha! Condensers rarely fail. Good fishing!"
