Your best way to find what you're looking for. Go to Johnson parts for your year motor, in the parts list it should list remote controls for your motor (they may show several controls), select the one that matches yours. Find the part(s) that you need to fix your control, write the part numbers and item name down. Then google each of the parts #'s you need with item name. Something should show up, or order from the nearest dealer, you could call that parts place, pre pay, and ask that they be sent directly to you.

If you order online, make sure you look at the pic for each part to verify it is what you are ordering.

Good luck, the parts pic diagram will be your best description for replacing parts. But you would be wise to take pics as you go, just to refresh your memory when putting back together.
