As for what Yamaha officially calls for when assembling the pump, this is their Gasket Maker:
Now I've seen many people who've pulled pumps and re-assembled without using this, and all the videos at the top of this thread also make no mention of Gasket Maker (they are dealer videos). So the need for this is limited IMHO.
Has anyone else snapped a bolt I barely put any force on it and it sheared off. They are soft and easy to drill and tap for the install of a new bolt. The boat is in salt water so it most likely gauled up the threads. The previous owner moored it for a season both wear rings needed replacement on a 2017, didn't get three years out of them. My previous 2005 still had original pump liners when sold in 2019 and I had removed all the bolts with no issues. Salt water destroys things if you leave the boat moored or docked.
