What To Look For On Used S Trim

It shouldn't have any effect, unless the cause of the engine failure was the blower coming apart. Check for a free turning shaft with no free play. The impeller shouldn't appear to have any nicks in it, and should not come into contact with the housing at all. I wouldn't worry if it has any stripped mounting holes, since it's easy to over torque the bolts in the aluminum housing. It's also easy to install a helicoil in a stripped hole. Good luck!

Depending on how catastrophic the failure, or slow occurring, it could have a major impact. Unless its a v7 it shares oil with the engine and could have had metal fragments run through it.
