I need help figuring out why my Trim motor quit working in the down position today it still works in the Up position fine just doesnt do anything when I press the down buttons I have two bttons for the down and two for the up on my Throttle handle and both the up's work and both of the downs do not.A little history its a 1993 Mariner 150hp and when I trim the motor up and leave a while it slowly creeps down real slow but none the less its giving.As for the trim working or not what could it be besides the Toggle switch or the motor itself? Thank you for anything that you may be able to tell me. i have to fix this myself because of Funds!
