Piranha's prop wrench is a multifunctional tool designed to work with any outboard or sterndrive propeller while providing additional benefits to boaters equipped with 4 Blade Piranha props. This model floats if dropped in the water instead of sinking straight to the bottom. The composite foam construction also makes the wrench non-corroding, even in the harshest salt water environment. The biggest improvement to the design is the modular prop nut insert system. This system allows the wrench to be fitted to most any Outboard or Sterndrive prop nuts in common use (Metric and Standard)!

If you are happy with the performance of your current aluminum propeller, order the same pitch in the Piranha.
If you are looking to gain speed, or lower your RPMs, increase your pitch. Every two inches higher in pitch will increase speed 3-5 mph, and decrease the RPMs by approximately 400.
If you are looking to gain hole shot, or increase your RPMs, decrease your pitch. Every two inches in pitch lower will cause you to gain approximately 400 RPMs.
If you are switching from a three blade to a four blade, drop one inch in pitch to compensate for the RPM change.
If you are switching from a four to a three blade, increase one inch in pitch.
If you have any questions about selecting the correct pitch, e-mail us and we will help determine what you need.
