Thanks guys for all the impute. I went to a Yamaha yesterday and picked up my 3 trim tab in 6 months. Talked to the guy at the desk and he said you should put a Lot of mussel behind putting one on. I think I will try a combo of all three ideas damage the threads approx ½ way up just a little bit, but extra mussel behind it hopping I don’t strip the Zink’s softer metal and maybe put a little tab of lock tight approx ½ the way up the threads so I still get a good grounding effect of the Zink and the bolt.
