Such great information guys, again thank you.
I have everything back together and I’m now pressure testing.
It’s holding 5lbs. I didn’t want to blow a seal. Is that enough or should
I pressurize a little more?

5# is over enough pressure for that gearcase. 2-3# is plenty.
Before running it make sure you run through the shift adjustment to accomplish full engagement of forward gear.
If you are not clear on this let us know. Myself or someone else knowledgeable will run you through the process.
