Propeller Details

• Application : The 18-inch diameter CNC Cleaver propellers are primarily designed for high-speed performance hulls such as offshore racers and catamarans with Mercury Racing sterndrives (e.g., M6, M8, or specific Bravo XR Sportmaster gearcases).
• Pitch Range : The available pitches for 18-inch diameter models are generally much higher than 21 inches, typically ranging from 30 to 40 inches, with some limited availability in the 26 to 29-inch range. The higher pitch is necessary to manage the immense power and high speeds associated with these engine packages.
• Outboard vs. Sterndrive : For 500 HP rated outboards (like the 500R), the maximum diameter offered is typically around 15.25 inches, with pitches from 26-40 inches. A 550 HP outboard engine rating is not a standard Mercury Racing product line, as power ratings jump from 500 HP to 600 HP (in sterndrive applications).
