It is primarily engineered for outboards and stern drives under 250 HP. Propeller Specifications * Brand/Model: Typhoon / Black Diamond * Diameter: 13-3/4” (total arc of the blade sweep) * Pitch: 21" (distance the prop moves forward in one full rotation) * Rotation: Right-Hand (Standard) * Blades: 3 * Material: Typically aluminum (standard) or stainless steel depending on the specific line variant. Performance Characteristics A 21" pitch propeller is considered a "high pitch" prop. It is built for higher top-end speeds because the boat travels a greater distance with each engine revolution. [1, 2, 3] * Best Uses: Recommended for lighter, faster boats requiring top-end speed. * Trade-offs: Because the engine has to work harder to turn a higher pitch, your "hole shot" (initial acceleration) and overall low-end pulling power will decrease compared to a lower-pitch prop (e.g., 17" or 19"). Compatibility & Hub Systems This propeller model generally requires a Flo-Torq II hub kit to adapt the inner splines to specific outboard or sterndrive models 15Splines (such as Mercury, Yamaha, Honda, or Suzuki). Ensure the number of spline teeth (usually 13 or 15) matches your specific engine's driveshaft.
