Lower Unit Gear Lube oil Change

[LKG4ME]

What size thread is used on the screw on the lower unit of a Volvo Penta 2009 SX-A when changing the gear oil - the one down behind the prop

Any chance you have a picture? I can’t find the drain plug on the SX-A.

 

[DO2G]

Does the prop need to be removed to get the drain plug?

Yes, the drain plug is behind the prop.
The level check plug is behind the plastic cover, near the shift arm.

3/8-16 is the thread side on my DPS-A drain plug.
Check to see if the part numbers are the same between the two outdrives.
