Check your mounts, pins, and castings for excessive wear, Not sure how 2001 boat is setup compared to my 70's boat, but I've replaced pins and ended up drilling out my castings and gudgeons (boat rudder mounts) and installed plastic inserts to take up the slop, works real well for me. Pins tend to wear out over time and use. depending on material they are made from.
Pictures of that, posted on here, tell it all.
Bow tangs you want tight, but not so tight they can't move alittle bit. Tighten when mast is up, Stainless steel washer under the stainless steel plastic inserted lock nut would work better than teflon washer in my personal opinion. Tighten the nuts up, if they loosen up again to much, from use, replace them. You can use loctite if you want, but I personally would'nt, just as alast resort.
Always use stainless steal hardware, all the more when it comes into contact with aluiminum.
