Winterizing 4.3 merc Alpha II this weekend

I am prepping my boat for storage this weekend. Anyone know what size o ring seals I need for the outdrive drain screws? Want to get them before I start on Saturday.

Do you have orings or the gaskets.
Orings are PN 12-19183, if your plugs have a groove in them for orings they are PN 25-805726
Both can be purchaced from any Merc IO or Outboard dealer.

Ayuh,... They're actually flat Gaskets,... They're available about anywhere selling marine parts...

Not always, some of the Gen II drives did have orings.

Changed my drive oil this summer and they were O rings (actually my mechanic did, I watched.). Just wondering what size they are so I can get them at the hardware store instead of driving 20 miles to the marine shop.
