Ultra 150 - Blowing exhaust tubes

[KennyMcAtee]

I have a 99 Ultra 150. I have had to replace both exhaust tubes twice this summer. When I flush the cooling system water appears to spit out where necessary. Ski runs like a champ. Any suggestions would be greatly appreciated

Soounds like something is clogging the pipe cooling spitters on the inside of the pipe. There should be a small squirter that squirts water INSIDE the pipe to cool the rubber hoses usually on the back end of the pipe ( stinger)
