3D Printed Outboard Propeller
thingiverse
This high-speed outboard propeller is designed to power any lightweight boat equipped with a 2-6hp outboard motor. In my case, I required a propeller with greater pitch for my homemade electric hydrofoil (3kw), which had previously been limited to a top speed of approximately 12kph due to its original propeller's design. The new propeller boasts a diameter of 200mm (~7.5 inches) and a pitch of 317mm (~12.5 inches). Unlike conventional propellers, this one features an actual airfoil for enhanced efficiency. During my small-scale test, the 3D-printed propeller performed flawlessly, demonstrating its ability to withstand the demands of higher speeds.
