Was riding today and hear a grinding noise and lost power, was towed to shore, and ski had taken on a lot of water. once I drained her, I notice a large gap on my carbon seal, also the driveshaft spines on the prop side were stripped (about 3/8 of the splines gone) it appears the driveshaft moved forward about 3/4" or so forward.. what could cause this? have not had a 4tec apart yet, so I am a little vague on the where and how the driveshaft connects and is supported to the back of
the engine. apreciate any and all advice. thanks! also lookign for a new driveshaft as well..
