Ebay is the only place I can find now, for about $45. We used to be able to get them off raidentech.com, two boats and free shipping was about $55. Parts are kinda scarce, anytime I find jet pumps on Ebay I snatch a few. They are a lot of fun with a little work, I recommend not removing the jet drive unless you really have to, you can replace the ESC/motor/servo in these boats pretty easily!
