ProBoat River Jet 23" pump impeller
thingiverse
Because the impeller and the jet hub are very brittle with gravel, I wanted to print and replace these parts when I want, without ordering a lot of original parts. Then I designed them as near as possible to the guenine parts with some improvements: The pump hub was designed to receive a bearing of 11mm external diameter. This is for easy realize the spider bracket mod. So the part is also suitable for non modified jets. Two versions of impeller are available : 1: original 2: a little bit modified to receive a m3 nut binder as you will see on the boat picture to use the bearing. Dimensions of my nut binder: 9X6.75 M3, flat head, hexagonal hollow, INOX. (warning: 9mm is the diameter of the head, 6.75mm is the nut lenght) References of my bearing: SMR115-2RS-INOX - 5x11x4 mm You will find information for spider bracket elimination in this thread: https://www.rcgroups.com/forums/showthread.php?2869771-River-Jet-Mods-Tips-and-Tricks
