Thanks for the reply.

I thought on to do what I should have done BEFORE posting and checked online.

You are correct APC don't recommend boiling. It turns out the prop is manufactured from a composite material and APC state NOT to subject props made from composite materials to too much moisture...
I guess that rules out boiling then !

The guy was trying to help when he suggested the prop would need boiling, I guess methods of manufacture and materials used move on and the advice was based on what he new from several years ago.
