I have a 1986 175 HP Mercury black max that I removed the carburetors to clean and kit. When I started to reassemble, I found about a 12" hose that looks like a vacuum hose that is attached to the throttle body that is the brass male fitting on the attached picture. I haven't been able to find a diagram that tells me where to attach the other end of this hose. I have attached a picture of the throttle body with the hose removed, as well the serial number badge. Any help would be greatly appreciated. ![[Linked Image]](https://texasfishingforum.com/forums/pics/userpics/2023/04/full-43553-179246-img_4057.jpg) ![[Linked Image]](https://texasfishingforum.com/forums/pics/userpics/2023/04/full-43553-179247-img_4058.jpg)

Does it go to the airbox that goes on top of the carbs?

I had not thought about that. I was searching for a landing spot on the block because I didn't want to go back together, then have to pull the carbs back off.
Thanks for the input.

Bottom corner, it sucks what fuel/oil mix puddles in the bottom of the air box into the crankcase to help keep the engine running clean and clear.
