Hello All, I have a Mercruiser MC-1 drive and I need to find the gaskets to put it back together. I'm looking for the gaskets that go inbetween the upper and lower drive (plus the waterpump p/n) and also the the gaskets between the drive and the bellhousing. My searches weren't sucessful. Thanks.

Everything you need comes in the full water pump kit , or the top half only kit. There are no gaskets per se just a small O ring for the oil passages called a "quad seal" 18-3316 should be the water pump kit 46-78400A2. Drive mounting gasket 18-2614 . Also get some contact cement or bellows adhesive.

Thanks everyone, I was having problems opening windows at work so I couldn't really search for much. I really appreciate it.

Boy I lost a lot of posts during the last refresh, someone was kind enough to post a video of replacing the water pump along with the part numbers of the parts I need. I looked at the diagrams but I guess I just don't get it, how do I know if it's the right drive (I have the MC-1), also how do I know if it's included in a kit? Thanks for all the help.

The only thing different in the water pump assembly between the MC-1/R and the MR/Alpha One is the base. All the top parts, including the impeller and all the gaskets are the same...
