| HP Torsional Prop Shaft 
 | 
    
      |  | 
        Replace your stock Mercury prop shaft with a new one-piece torsional shaft for those high performance boaters. Don't take a chance of losing your favorite prop. Torsional prop shafts offer better torsional load flexing which eliminates brittle fracture or breaking associated with non-torsional units.
