I have a 2012 130 etec trim tilt works on and off up or down does not matter. i've put new batteries in boat, I've fooled around with relay. I've also bypassed the limit switch, to no avail. When it does not work, if I tap the tilt motor with a wrench it will work. It will work for a while then all of a sudden not. The engine was jerking bad in down mode for a while I tightened the pivot rod nut and greased, that seemed to correct that problem. But still problem with up and down. Any suggestions?
