Identify Evinrude Engine Part from Photo

I am fixing up a 1996 Evinrude 48SPL. See Figure 1 below, and identify the hose and its purpose.
The hose seen in Figure 1 above attaches to a fitting that looks to me to be screwed into the engine crank case. The [other end of the] hose is plugged, so whatever its function was, it has been defeated. The usual drain hose from the bottom of the intake manifold to the air box is there where it belongs.
ASIDE
This engine came with a set of remote controls that used the System Check which consisted of gauges and sensors to alert you to problems. I don't know what kind sensor would read crank case pressure/vacuum, and for what purpose.
I also think the remote controls are not the ones that belong to this engine. It had trim-and-tilt on the throttle as well as all the System Check wiring. The SPL engines had no oil injection, tilt, or regulated charging. It is even possible this powerhead has been replaced with something different.
