Last weekend I hit a bigger than usual wave and my motor shoved my trim cylinder all the way down....and i could hear the trim cylinder working tryng to trim the motor down. I could hit the trim button on the controls and hold it up to stop it but once i let go it would start again...the trim control on the motor wouldn't do anything to it. I taped the trim button up to stop it and headed back to weigh in and about 5 minutes in the trim came up and started working fine. My partner said maybe the cylinder was building pressure? Did I hurt my trim unit? Does anyone have any ideas or had this happen to them? It seems to be working fine now. 2018 115 pro xs.
