High Speed Propeller
High-speed propeller is a kind of ship with high speed and fast sailing. It has 3, 4. 5, six and 7 blades, small hub and large ratio of blade surface to disk surface. Usually the engine is high rpm and gear box ratio is less than 2.5:1, so its propeller rpm gets more than 650, it needs big DAR and high speed design, if we use normal design propeller for the high speed boat, it will come out problem for the engine like wasting the fuel and oil of the engine and the boat speed is not fast and all the efficiency will come down.

Product Introduction
High-speed propeller is a kind of ship with high speed and fast sailing. It has 3, 4. 5, six and 7 blades, small hub and large ratio of blade surface to disk surface. Usually the engine is high rpm and gear box ratio is less than 2.5:1, so its propeller rpm gets more than 650, it needs big DAR and high speed design, if we use normal design propeller for the high speed boat, it will come out problem for the engine like wasting the fuel and oil of the engine and the boat speed is not fast and all the efficiency will come down. So use normal design propeller for the high speed boat will be a lost of wasting time and energy.
Also, when we making the high speed propeller in the sand moding it also come more difficult to complete the work. So the high speed propeller is lighter weight much better and cost higher laber and moding and machining.
