I'm ready to pull the trigger on a set of 8' Raptors for my 20' Gambler but I'm worried they may not fit in my garage. How can I find out how High above the top edge of the jackplate they will sit? Thinking I'd get the 4" brackets vs the 6" unless there's a reason for one over the other. I do have another 18' gambler that sits in my other bay that has a set of minn Kota 12' Talons and they barely fit. Slightly deploying the raptors is not an option as my bigger boat is backed all the way tight to the back wall to allow the garage door to close.
