My speedometer has not been working for a while. While we were winterizing the outdrive I tried to find out if the line was plugged and I found out the line was disconnected from the outdrive. Upon further inspection I found that this small piece was broken. I removed the piece from the outdrive and I have been searching for the replacement part but so far have come up short. Does anyone have an idea where I can get this part? The part goes into the lower part of the drive and has a small connection that is broken in the bottom of this picture.

Here is the info on my drive unit:
Drive Unit
DPS-A 1.78

Thanks
