Re: 50’s Johnson gear lube substitute?

Lubriplate 105 is also a good choice in manual shift gearcases with minor leaks. Many have and still do use it. John Deere Corn Head is, more or less, used interchangeably with Lubriplate 105 for this purpose. In my limited experience, Corn Head Grease is a less expensive and more available alternative that works as well or better in non-shift, and manual shift outboard gearcases. I still prefer to reseal and use gear oil in cases that are repairable, but either grease is an acceptable alternative in most cases. Others with more or different experience may have more to add.
