I just put on my true tracker from BMS. I lined it up perfect so the circle hole on the bottom was perfectly around my zinc under the cavitation plate, drilled bolted, stood back to admire my work....but now I’m second guessing. Is it ok that there is that gap between the cavitation plate and the BMS plate? I ordered the 40+ hp model for my 60 hp Yamaha. I’m kind of in a buyers remorse panic
