About boat propellers...

• Always have three spare blades on hand in your boat, with the floating wrench. If, you happen to hit something in the water while you are traveling, all you have to do is, make land and change the blade in only a few minutes. That’s the beauty of the Piranha Propeller.
  
  
• With the same Hub you can change the blades according to the activity you are doing. Whether it is water ski or just going around for pleasure. In a mater of minutes, you can fit your propeller with a new pitch blade.
