Sea Drives don't pivot where a conventional outboard does (ie; at the base of the powerhead). They are mounted to a two piece bracket. One half is stationary and mounted to the transom. The other half that the motor is mounted to pivots off of the stationary half at a point that's right about at the top of the powerhead. That's how they were able to be mounted closer to the transom. If you put your hands together with the palms flat against each other, pivot your wrist of one hand away from the other keeping your finger tips together. ;)
I worked at the Boston Whaler factory years ago and they used many of those Sea Drives when they first became popular back in the early '80's. I'm quite familiar with them.
