I have a 2021 Nitro Z18 with a 150 Pro XS. Purchased a MTOS bracket to be mounted between motor and transom to bolt power poles to. The MTOS bracket was too wide and The shop was going to have to cut off the D rings, rings for tie down straps, in order to make it fit. I told him I didn't want to do that so he said he could install a jackplate and that would take care of that problem. Well, I decided for him to install an Atlas mechanical jackplate. He calls today and says he is having the same problem. I installed a MTOS bracket on a 2019 Z18 with no problem. Has anyone else ever had this problem?
