My Quicksilver single lever Throttle/Shifter is self-destructing! First had to super-glue plastic plate covering trim & trailer switches. Now the UP of the TRIM switch failed. Down Trim still works & I can trim up by using Trailer switch. Has anyone replaced the TRIM switch or do I need to replace whole Throttle/Shifter? Has anyone found a good reasonably priced replacement or must I do e-bay for original Quicksilver single lever? The experience on this site has been invaluable. Any solutions will be appreciated
