Hello I have a 1984 Procraft 1650V with an Evinrude 115 4cy. My problem is that the trim will not lower down. It raises fine and when I press down I can hear the motor and things turning but I have to manually lower the unit. Any idea what is wrong and is this something i can fix or do i need to take it in?
