Need a little help. I bought a 1997 artic cat tiger shark 770. Machine is in amazing condition. Took it out first time and ran it for about 20 minutes. I then just idled around a bit and when I went to get back up it wouldn’t open up. Found water on plugs. Dried everything out and took it back to lake. Ripped it for about 2 hours with 0 issues and then the water on plug issue happened again? Any idea what causes this and how I can fix it?
