I don't understand how my 2002 90 HP 2 Stroke TLRA has worked these last few years. I'm chasing a different problem but when I took the lower unit off I was expecting to have to disconnect the water hose that pushes water back up to the engine from the water pump. It isn't connected though. However, somehow when I run the motor in the water it still has water spray out of the place its supposed to. I noticed that other people's engines online have a clean looking stream come out of the engine, but mine has always sprayed wide but figured as long as water is coming out oh well.
So I looked at the parts diagram it looks like there's a water hose that goes... no where. Even says it ends at "End, Nipple".

I don't understand what the point of it is, and it seems that the person who owned my boat before me also didn't considering it was just hanging off of the back of the engine doing nothing. You can see it laying on the boards, it's never been actually connected but the engine has always still cooled with water spraying out.
I also was wondering what the point of Part 11, it is called a Damper, Seal. The location where I found it seemed to be corroding out. Not the seal itself but where it sits. There was a lot of buildup there but as I used a toothbrush to get it out I noticed it looks like its corroding away the metal. I was wondering what would happen if that thing wasn't set properly and whatever it was sealing was failing what would happen.
