Hey guys I installed a humminbird lcd, the model number slips my mind, last winter on my center console aluminum boat. It has been working fine. But here lately while I am running down the river the screen clears out. I usually pop it off the bracket and slip it back on and it works fine IF i keep some hand pressure on it while running. I am sure its the vibration, but how can i tighten it down. I have always despised humminbird quik mount deal
