Replacement propeller for electric outboard motor Haswing W20. I had troubles with the original propeller since the motor started oscillating when the boat was moving fast. This happens for example when the wind comes from behind or paddling additionally. I could not figure out where this comes from since the propeller seemed to have no major imbalance. So I created a 3 bladed and 5 bladed version since more blades should improve the smoothness and I increased the steepness a bit. This makes the propeller running at lower speeds to take the same power. However it increases the load on the motor and more blades reduce the efficiency in theory. The increased load could harm the motor. I printed it from PLA and it survived a few hours of operation already. I prefer the 3 bladed one. There is as well the single cone available if you want to design your own blades. This is not an official replacement propeller, use it carefully and at your own risk! Parts of the propeller could break and hit a person at high speeds which can cause injuries!
