Not being familiar with any outboard but Mercury/Evinrude, I began looking for the lower unit drain plug on my recenly acquired Force 85. With a bit of help, I found it. Problem: Allen wrench wiped the corners of the allen screw drain plug. I drilled through it, with the idea of using an "Easy Out" for removing the rest of the screw, but it will not budge (I've leaned on it heavily). Any suggestions? My thought is to continue drilling out the allen screw until (1) it's all gone and I still have some good thread left; or (2) I drill and tap to the next larger size. Wondering what others might think of this situation. Thanks for any help you may provide. Gary
