OK I just bought a 1998 Sea Doo XP with the 951cc engine. I am having a problem with blowing holes in the rubber exhaust boots connecting the manifold pipe to the rear pipe. This has happened twice now within 15 minutes of riding. Also The small hose connecting to the side of the exhaust manifold by the head also blows out. not sure whats the problem is but once it blows od the boot and hose the ski fills with exhaust and kills the engine from lack of oxygen. If you have any ideas please let me know.
