OTTER USE THIS SEAL
If you are rebuilding Ford V8 marine engines from the 80’s and 90’s, the marine reverse rotation 1-piece rear main seals can be expensive and almost impossible to find. The late model PTFE rear seals are non-directional and make a great seal to use in these applications. The PTFE option will work great on your late model GM marine engines as well. Always follow the manufacturer’s installation instructions.
