Spark plugs for Evinrude 90hp

[beer batter]

I need to replace the plugs on my outboard 2 stroke 1983 Evinrude 90 hp 4 cylinder but I forgot to check the number on the plugs and now the boat is 2 hrs away. Anybody know what number plug I'd need for that model engine so I can purchase before getting to the boat and then having to drive 45 minutes back to a store to get them?

You can go to any auto parts store, Fleet Farm, marine dealer, etc.. who sells plugs. There is always a spark plug reference guide (thick book) right with the plugs on the shelf. Just look up the motor and it should give you the plug #. I do it all them time when I forget to write the #s down.
