Winterization:
From my experience with Performance Propeller winterization, if prior to taking your boat in for winterization the temperature drops to 32 degrees or lower for even 10 minutes they provide no guarantee against freeze damage. In my case a hard-freeze had not yet occurred, only 31 degrees for 1 hour on 2 occasions prior to the winterization and a court ruled in his favor.
