I have a 1977 mcm 233 mercruiser serial number 4883963 with what I believe is a mercruiser 1 drive. I thought it was an alpha one. Serial number is 4794847. It is unclear on what shift cable I need. It stripped inside the cable end guide where it goes into the anchor screw. I'm not sure if I need the 63" cable with a support tube (18-2158). Or the 54" without one (18-2248). I've gotten a lot of different part numbers. The 18-2603 comes with all the gaskets and cable slide I need, but is for an alpha one. I feel like I just need the core wire, anchor screw, and new cable slide for my issue. As my set screw is corroded. Can I just get a core wire and feed it through my existing sleeve? Also the 18-2614 are the correct gasket and o rings for my outdrive? I have no oem part numbers to go off. Thanks so much for the help. I've been researching cables for days now.
