lower unit drain plug size

Hey Guys

I'm trying to find out what size the drain plug is, so that a can get a air fitting for a pressure test. Any help?

Take your drain plug out and measure it. You can get a thread gauge from Sears or almost any auto parts store.

Or, if you have the fitting for adding gear oil to a Yamaha motor measure that.
