Hi New to pwc.

Just bought a 2000 virage tx 1200

Had it out today and the bolts for the exhaust loosened up and started filling the inside of the ski with water. I took it home tightened up the bolts but it still leaks a little. Should I just put a new gasket in??

I was starting really hard, I was hoping its due to getting a little water into the engine from the leak.??

Also is there any way of knowing if the lock code has been changed??
I know the factory code is 1234 but I don't want to lock it and not be able to unlock if the code was changed.??

Thank you!!!
