This year I installed a Garelick lifter for my Yamaha 9.9 high thrust
4 stroke. It is a somewhat heavy (100 lb.) engine, and thus the
necessity for an assisted lifter.

Does yours a fully-manual-motor-lifter or a hydraulic-assisted /
manually-operated motor-lifter? I see that Garelick has a
hydraulic-assisted / manually-operated motor-lifter. But I am not sure
how well it works considering the fact that I have a "container" (box)
right in front of the kicker. If I used a manually operated motor
lifter, that "container" would get in the way when I tried to lift the
motor up, and I would have to bending my back in an awkward angle.
That is the reason why I want the powered trim option.

What I did to support the engine was buy a big piece of stainless
steel plating, which I used as a backing plate for the Garelick.
This distributes the load across a larger area of the transom.

Thanks for the suggestion of using a SS backing plate. How thick the
backing plate do you need for your 9.9hp motor?

... I also was worried about the engine hitting the transom when
fully tilted up. ...

I don't quite understand. Why do you need to tilt up the motor? If
your motor lifter is going to lift the motor straight up and down
vertically, it should not need to be tilted up, and it should never hit
the transom, right?
