Re: what did you do to your motor bike today?
It's known that Kiekhaefer Mercury runs a high copper content in their engine castings to lessen galvanic reaction and corrosion.
But Never-Seize is ALWAYS a good idea on ANY important threads !
Especially in aluminum!!!
Family experience tells me the silver Never-Seize product is good down to 14kft submersion, on undersea mining equipment that was impossible to repair prior to it's use, without a torch to cut the nuts off the bolts.
