Sho Plug question
I am changing out my plugs on my 08 SHO and noticed that it called for a ? #527? loctite for the bolts holding the plug wires on. Is this really necessary and/or can I substitute for another loctite? Thanks as I don't know if I can locate this loctite today and really wanted to get this done and out on the lake. Thanks!

I don't think I have used anything but torque on sparkplugs in any motor in my life.
Interested in seeing what others might say.

A splash of any threadlock will do if you have to use any,but just dont use as much as yamaha uses damn they coat the bolts in it

Thanks, the coil bolts were actually very easy to take out. I did tighten them good but will keep an eye on them. Easy plug removal/replace though. Thanks for the quick response. We have 72 degree temps today and wanted to get out on the lake.

Loctite 572 is a thread sealer & light locking compound. It is an acrylic paste that drys to a rubber like consistency & is different to the red or blue threadlock.
I have always used it on my HO, but like the others have said, as long as the bolts are torqued up correctly, I can't really see them coming undone.

Interesting to read this. I watched the mechanic do the 10 hour service on my SHO. He used a small amount of waterproof grease on the spark plug threads and bolts holding the coils and then torqued them down. He has said that based on his experience here in AUS of mostly salt water riding, he has seen too many plugs corroded into the cyliner head and were unable to be removed without taking the head off the engine.
I will keep an eye on the bolts as well, but his method certainly made sense to me as far as being able to reduce salt water corrosion.
