If you run at full throttle with a propeller selected for acceleration and not top-end speed, your engine rpm may be too high, placing an undesirable stress on the engine. If you select too high of a pitch, your engine may lug at a lower rpm – which can also cause damage. Acceleration will be slower as well. It will be reduced further with a full load of fuel and maximum capacity of people on board.Propeller pitch selection allows the engine to operate near the top of its recommended rpm range at light load (1/2 fuel tank and two people). Using this pitch selection method, the engine usually operates near the low end of the recommended engine operating range when the boat is fully loaded (full fuel tank, boating gear, full live wells, and maximum capacity). Full load engine speed is usually reduced 200 to 300 rpm. The power output of naturally aspirated engines can be affected by high heat and humidity which is another factor that can reduce engine speed by 200 to 300 rpm.CNC machining processing stainless steel propeller.Lathe processing small bronze propellerLathe processing large bronze propellerUse the robot hand to polish the surface of the propeller to achieve the required shape and thicknessManually polish the finer positions to achieve more precise precisionDynamic balance detectorSmall propellers can be detected by dynamic balance detectorStatic balance detectorLarge propellers can be detected by dynamic balance detectorQ1.
