Well my project has come to the point when I am installing my drive (IMCO SC) to ITS and I have a question about sealing the drive to bellhousing. I have the orings for water pick up, shifter cable and oil but feel like there should be a oring to seal the dive to bellhousing or at least some sealant. Pics below to help if my explanation was not clear.

I assume it's the same as all Bravo drives and doesn't have any seal or O-ring.....

Yes , same as bravo. How does it seal ? Just seems like a flat surface?

The snout of the drive pushes on the bellow sleeve( the aluminum piece
inside of the bellow) and as you draw it in, it compresses the bellow end
to seal against inside of the bell housing

Oh i understand now. Thank you.

Hey, just to be clear JT is correct. When installing the Bellows there is a groove on the Helmet and a groove on the rubber. It fits very nicely into the first groove but you must pull the bellows into the second position thus moving the rubber surface further aft. If you do not put into the second groove it will not seal. Check the manual for correct pics and such. You really have to wrestle it into the second groove and it seems it should go into the first but the first is incorrect.

Does anyone have a scan or link to the manual for the correct pics of the groove etc?
