WebbDetermine from your weight and balance calculations whether you need a heavier prop (metal) or a light (wood) propeller. The wood prop will be lighter by about 10 pounds for the smaller engines. Considering the higher cost for metal propellers, I wonder why more builders are not using wooden propellers. For most vessels, a small increase in diameter means a dramatic increase in thrust and torque. In higher speed vessels like mentioned above, however, a larger diameter equates to high drag. Diameter generally increases for props on slower boats and decreases on faster boats. Pitch Ratio of Your Propeller Visa mer The propeller pitch is the distance that a propeller would move in one revolutionif it were moving through a soft solid, like a screw through wood. It … Visa mer The lower the propeller pitch, the better your “hole-shot”, or ability to get up to speed very quickly from a standstill.
