Hey is just rebuilt an seadoo 951 rx(carb) and it bit the dust when i was riding one day. We have 140-150 psi in each of the cylenders. And we weren't sure what broke. Then i popped of the reed block and there was orange rubber. The only orange rubber is the inside seal from sbt's rebuilt crank. I'm pretty sure this seal is toast. Due i need a new seal or rebuilt crank? will sbt cover this? in there no fault warrenty or am i paying to fix. My engine has about 10 to 12hours on it sence we rebuilt with there parts.:(
