Piranha performance kits offer all the same benefits as our popular Propulsion kits, but they add a little extra performance boost from the inclusion of a Piranha Hydrofoil Stabilizer.
The hydrofoil bolts to the anti-ventilation plate on your drive and provides useful sternlift to your boat. The hydrodynamic lift it generates helps your boat get on plane faster and usually at a lower speed. This is most useful if you tend to run your boat heavily loaded or if you want any easier time pulling up skiers.
Macomb Marine Parts and Accessories primary objective is to achieve the best performance from your boat. Macomb Marine Parts and Accessories recognizes Piranha Propellers "Blade Exchange Program". This program allows you to test and exchange undamaged blades until you are satisfied with the performance of the product. Please click here to exchange your blades.
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.
