I have a 2001 seadoo gtx rfi. 787 motor. I was riding today and all of the sudden I dropped to 3k rpms and then started shaking. I pulled the key and restarted and it ran perfectly. Once I got it out about 2 hours later I see my battery on the opposite side of the ski and I notice this crack by where the driveshaft exits the hull. How do I go about fixing this or is my entire hull trash?? PLEASE HELP!!!!
