A parametric ROV thruster propeller. The design assumes the ROV moves slow when compared to an RC boat. The propeller is more similar to a tug than a speed boat. Close to equal efficiencies in both directions of operation Using at 750KV brushless motor the propeller and nozzle provided 14N of thrust in both directions drawing 6 amps at 12volts. Number of blades, prop diameter and thickness, pitch, shaft hole are all modifiable in the openSCAD file.printed using .1mm layer thickness, using platform support density of 20% on a MOST delta printer.
