The Spray Jetboat Hardware list
Updated: Feb 2, 2021
Not all things can be 3D printed of course, though I'm sure some have tried. The following items is a list of hardware components we have used and recommend to complete your Spray jet boat. I've provided links in the description. You will notice on some of the hardware there is a number string after. For example 91223A411 under pitch adjuster hardware.

They are a fantastic site for purchasing hardware, but unfortunately you will likely have to buy in larger quantities than you need. Nevertheless they have an awesome product search tool that you can reference
