Seadoo supercharged cutting out

I have a seadoo supercharged that has been working fine for two years. Recently it started cutting out(prop would spin for a few seconds then stop). In the past that was a battery issue and I would recharge. Kept cutting out after battery recharge. So I bought two new batteries, charged them and the same thing happened. So I bought a new charger. Still the same thing happened. So I opened it up and saw water in the electric area. Ordered a new circuit board and replaced old one. Still cutting out. I cannot get it to keep running for more than a few seconds at a time. I used a magnet to check to make sure it was not a connection problem between the magnet and the electric circuit. Kept cutting out. What do I do now? I have spent more on parts than the thing is worth.

I own a VS supercharged Plus as well. I think I'm going to have to replace my circuit board. Did you replace the circuit board yourself? If so, how did you get the battery tray to pop out of the shell? I've loosened all 4 screws at the bottom of my battery tray, but can't seem to get the tray to slide out.

It has suction like the top chamber. You need to just give it a good pull. I replaced the circuit board and it did not help. It still cuts out. I have replaced everything and have no idea what to do now.
