My Nexus 6P got water damaged, What will I need to replace?

Hi

Before you replace anything, perhaps try cleaning all your boards properly in isopropyl rubbing alcohol and all the connectors. This may restore the device to working order without the need for replacement components.

Thanks!

I agree with Larry. Clean everything first! I had a similar instance happen with me, and after a thorough cleaning of corrosion, my phone booted up perfectly! However, I came to realize that the microphone in the daughterboard failed. It was a pretty cheap $20 part though. Depending upon where the water damage occurred may tell you what area of parts need replaced. In general, it is a good idea to test all the functions of the device if/when you can get it to boot up. This will help you further decide.
