Hobie Outback Motor Mount

Hi all - quick question on a potential Hobie Outback Motor Mount. Just a quick background, I currently cartop my Hobie Outback and plan to do so for the next couple of years until no longer feasible which at that time, I will need to invest in a trailer/SUV(still to be determined).

The main question I have sounds the motor mount for the back of the kayak. Since I cartop my kayak and use a Rhino rack to help, is there a specific motor mount that I should be looking for. I would need something that I could easily remove the motor off the back after use. My main concern is whether the bumper/loader that is used when loading will be impacted with the fastening mechanism and if there's enough room on the back so that the mount doesn't scrape the ground when loading the kayak onto the Rhino rack.

I've searched throughout the internet and haven't found any discussions on this so any insight would be helpful.

thanks
