just got my waverunner back from the shop (rebuilt carbs) and took it out, ran great....however when flushing it out I noticed the 2 bolts that bolt the exhaust to the engine were loose. I tightened 1 and the other appears to be stripped (the hole, not the bolt). Tigthened the one, took it out again and it loosened. My question, will lock tite be able to prevent it from loosening w/ the high temp? Any recommentdations on that? Also, what can you do when the hole is stripped? JB WELD or something like that? Thanks for the help in advance.
