O-Ring / Washer Sizes 96 Johnny 50hp

[ShellBack101]

I was hoping that someone could help me out with the Oring / Washer Sizes for a 1996 Johnson 50hp Lower Unit Drain and Fill Plug (top and bottom screws). OMC part Numbers:
336982 (upper oring)
311598 (lower washer)
333572 (lower Oring)

I am trying to avoid ordering them online and paying $10. shipping on .50 cents worth of stuff i can get at a hardware store. I would just pull the plugs and take them to a store but right now the boat is quite a distance from home. Thanks

Even if you knew the size, the material and durometer (hardness) is very important to hold up against salt water and lube oil. Not sure if they are ordinary Buna-N (neoprene) which you will find in any hardware.
