From the center of the shaft to the front outside edge of the motor housing is 3-1/2 inches. I included some of the mounting plate when I measured for height, which is 8-1/4 inches, since that sticks out over the shaft as well. I also measured from the bracket that fixes to your trailer's A-frame to the bottom of the mounting plate for the motor and that measured 13 inches. See included picture for a visual. To make sure that you have a secure power connection to the jack motor I recommend...

The Ultra-Fab Protective Cover for Electric A-Frame Jacks - Vinyl - 12" x 14-1/2" # UF38-944020 is the protective cover I recommend for your Husky Brute 4,500 lb Trailer Jack # HT87247. I've attached a photo of the dimensions when laid flat, but I've also attached a video to assist with the fit. It has a durable vinyl construction with integrated draw string closure.
The cover has worked great. The reason for only 4 stars is that we took preventative measures when it arrived. Many reviews complained about it leaking. We turned it inside out and sealed all the seams. Once dry, we put a plastic bag on first and then this cover. Using both has made a water/weather proof cover to protect the electronics of our power lift. The plastic on its own is not strong enough, adding this cover made the difference.
