Yamaha Parts, On-Line Link (Owner's Manuals Can Be Found Here Also)

Here's the link to the official Yamaha Parts web page. All you need to do is select:

1. outboard
2. year (located on a plate on your engine mounting bracket, usually starboard side.)
3. model (located on another plate on the engine mounting bracket, port side)

Things like the "trim cam sender" can be found with a little searching. The hardest part is knowing which option on the left to select to find what you're looking for.
