Power?
Hello Robyn and welcome to the Seadoo forum. You may have a blown fuse and since you don't describe any other funtions working at all, maybe that is where you should start. Look in the compartnment in and around the engine for a sealed black box. You'll know it's your electrical/mpem box from all the wires you'll see going into it. This is where you'll find all your fuses. I'd start there.
We do have your manual in the forum. I just looked at it to get you this information. The premium section is available for a small fee and has an extensive library of Seadoo shop manuals along with operators guides and wiring diagrams.
Let me know if I can help you further. Welcome to the forum. :cheers:
