This is an improved jet pump originally made for the NQD jet boat but suitable for other shallow-angled bottom boats. I will publish servo mounts for the NQD jet boat after the winter break. This pump is approximately twice the size of the original pump that came in the boat so be weary of component placement. This pump is also designed to work in conjunction with the included file for the reverse bucket so that will of course require a second servo and a piece of light weight spring wire (approx. 1-2mm landing gear wire is the same thing). This pump is designed to be powered by the Velineon V3m system but would probably work with any 380 size brushless motors with the same hole configuration. And please note that this system is designed to work with a 1/8th inch rod as the drive rod!!!

Doesn't Matter








Please note that the impeller, jet director, and reverse bucket where designed to be scaled by a factor of 1.2 as I hadn't planned to put this design up. Note that when printing the reverse bucket it should be flipped 197° and printed with support at an overhang threshold of 55°; cleanup for this part is a pain in the a$$! All other parts can be printed with support and an overhang threshold of 0°. Printed fine at 80mm/s.

Can this print run with tough PLA? I only can use this fill.. please advise

Awesome design and thanks for sharing! Do you have any videos of the jet pump working in your boat? Have you posted this on any forums?

Thanks! No, I do not have any videos of it running although from my dry runs it seemed to work function as expected. As I was making it other things in life happened and I had to devote my time and money elsewhere and so I never got the electronics suit I wanted to put in it. Hopefully I can get back to that soon. If you try it please let me know your thoughts so I can fix anything!
