80-90W gear oil is indeed acceptable for my mercruiser one drive.

Wanted to look at the old fluid.

Emptied into mason jar, Got about 30-34 oz out of the drive.

Looks good, no burnt smell, no water, no shavings.

Re: Just making sure

And, replace the orings under the screws correct?

Can I just go to home depot and buy them, or are they "special" and need to be bought from a marine supplier?
