Cleaver XB Replacement Blade Set 13 x 19 1319XB
Different from most Piranha Blades because it features a semi-cleaver blade shape. This gives it the straight looking, uncupped trailing edge you see. The thickness of the blade is also thinner than Piranha's cupped blade designs. This allows these blades to achieve higher RPM and often a higher top speed.
These blades will not work correctly on some brands of outboard motors. Common applications that do not work correctly with these blades are Mercury, Johnson, and Evinrude. If you are not sure if a semi-cleaver blade is appropriate for your use, please contact us for a recommendation.

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.
