Well, not sure what to tell you about your Westinghouse/Chysler/Force motor there Jack. They haven't made them in over 10 years and a lot of the parts are already getting scarce. The lower unit and gears are notoriously under built and if you do happen to find those parts, you're going to be shocked at the prices. On the plus side, their cooling systems were pretty good, but the head gaskets were easy to burn up. These motors were also way over rated and a 9.9 runs more like a Johnson or Mercury 6hp.
If you need any guidance, parts or advice on this or any other outboard, go to the iboats.com forum and you have a great wealth of knowledge there. I post there under "Tronald" from time to time to ask questions about motors that are giving me some trouble.
Good luck!
