While placing the cowl on my engine, I noticed an open ended rubber tube (approx18-24) was dangling from a black tee that is the tell tale. The tee also has another rubber tube that leads to the engine and is completely intact. I cant seem to locate where on the engine this open ended tube connects to. This engine is 1985 140 Evinrude vro which is NOT the original block. It is a remanufactured powerhead that I purchased 2 seasons ago. Could it be that my original engine was configured differently. Had the engine VRO system updated.<br />Thanks for your help.
