There was a time when there
was no lack light weight grease
packaged for outboard motor
gear cases. As demand dwindled
they were discontinued.
Substitute for these greases are
105 grease & corn head grease.
The performance of lubricants
has really improved over time
so these grease’s are probably
better than those shown below
but back when they were
casting "Grease" on a gear case
you had plenty to chose from.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
