Part 1: 1976 Mercury 20 HP Outboard Lower Gear Unit And Oil Seal

Tune-up on my lower gear unit. Multi-part series as I refurbished my 16’ Gregor. I’m not a mechanic, so it’s a “learn as I go” video. As I began this project, it morphed into something bigger. I now have the motor off and the transom removed. I'll post more parts to the project as I go.
