New Tilt Trim Question

I forgot to mention. How much oil should it take?

There is a VENT screw on the pump not far from the fill hole on top of the reservoir. Should I fill till it pours out the vent hole?

Is it possible to overfill?

I ran thru working the drive up and down a couple of times to work the air out and it seemed to be working ok.

Would this also cause the drive to raise and lower so slowly?

Thanks you in advance. I really apprecaite the advice.
