-trying to get the new boat out on the water

-there are two places to change the oil. upper and lower. I used the westmarine lower unit oil in both placeswith the oil pump. does this oil work for both? How do you know all of the air bubbles are out of the case?

I hope you used Type C oil in that electric shift drive.

Did you fill from the bottom hole?

If it is a 1972 omc, it is an electric shift.
