The bottom is still a slot. My 2007 Yamaha 2-stroke is mounted 3 holes up and the bottom bolt is near the top of the slot. It was mentioned on this thread or another that you can drill the bottom holes after raising the motor and attaching with the top bolts. I did that on this boat and it works. With the motor completely off, I would use the measurements given by Joe and drill the green holes. That is what I did on my other 16' and it worked fine also.

Your splash well is probably deeper than mine but you may have to angle the drill bit slightly upward when you drill. Others with a Montauk of similar age could tell you for sure, or just measure down from the transom notch.
