question about little nipple on throttle body...

[Carboncow]

Isn't this the nipple that's connected to a tube that runs up on top of the plastic engine cover? In the picture a few posts up, it is the yellow capped nipple on the plastic cover. It allows you to lubricate the TB easily.

Thanks Joe. Ubiquity did note that a few posts above. For whatever reason my boat doesn't have the tube or attachment point on the engine cover. I don't recall if there is even a hole so I will report back.

The cover has s slot on it. The tube slides into the slot.

Found this pic of the cover.
