Hi everyone. I finally have the new stern drive unit installed and ready for oil. Boat has been de-winterized. Oil and filter changed, belts checked, battery slow charged and checked, Cables ok, electrical....check, hydraulics....A-ok, new gaskets, billows and o-rings between the bran-spankin new drive unit. All I need to know is how much oil will it accept? I have a full quart in it but none has came out the top yet. does it need more? Thanks in advance. I looked thru the search tool but found nada....
