Don’t have a clear recollection of filling the
gear case. Likely just put in what it would
take to avoid over filling. Don’t know how
extensively you plan to use yours. I was
checking (let the water drain out) and adding
grease as needed the time I was using one
daily. I used how many tanks of gas I ran to
determine when it was time to add more. The
condition of the bushings dictates how often
that will be. Want make sure all the water is
out of the gear case when you’re done. The
screw on the side of the water pump is to drain
the power head. Don’t loose it as screws with
that thread are no longer being manufactured.
While wheel bearing grease will stay in there
longer, using 105 or corn head grease will give
the upper driveshaft bushing as well as the prop
shaft bushing the best chance of getting
lubricated. Search you tube for
“Lubriplate 105 – Corn Head Grease – in
Antique Outboards Without Seals”
If you’re not aware of the grease we use today
as a substitute for what is no longer available.
