Re: OMC exhaust?
That's your exhaust bellows.
It's not a problem........... Mine ran for about 10 years with NO exhaust bellows with no apparent problems...
If the exhaust bellows is old and cracked etc.....the drive bellows might be bad....THAT IS A VERY BIG PROBLEM. You should remove the drive and check the alignment and U-joints before running it if it hasn't been done in the last year or so.
The oil should be replaced once a year or so too.
It's appropriate to start a new thread for a new/different problem.
I assume we're talking about a Cobra. See my reply on your other thread. You need a manual and that Hastings article to understand what you need to know about the Cobra.
