For the second time my 2019 mercury 75 hp 4 stroke has gotten stuck in the completely down trim position. The first time was on the water and it eventually corrected itself. Yesterday it was stuck in the down position as I was taking out. It appears there is no power to the upward trim switch ( switches ). Eventually, by having someone pull up on the motor as I pressed the switch it began to trim up, and continued to work properly. Does anyone know of a cause and a solution to this issue.
