The file '3D Printed Outboard Propeller 3D Printer Model' is (stl,stp) file type, size is 1.2MB.
This is a high speed outboard propeller for any kind of lightweight boat with a 2-6hp outboard.
In my case i've needed a propeller with more pitch for my homemade electic hydrofoil (3kw). The old propeller was only designed to go up to ~12kph, but since I have much less friction I could achieve a much higher speed with an appropriate Propeller.
This Propeller has a diameter of 200mm(~7.5'') and a pitch of 317mm(~12.5'') and unlike conventional propellers this one has an real airfoil for really good efficiency.
In my little test the 3d printed propeller held up perfectly.
