Sorry for the stupid question I know this has to be a simple fix but I’m new and having issues. I broke the connector to my speedometer tube where it hooks to the lower unit. It is a Mercruiser Alpha One serial# 0F679154 attached to a 1996 Crownline. I can not figure out what new part exactly to order or how to get this old part removed. I know it has to disconnect easily for separation of the lower unit during maintenance but I can not get anything to move or come apart and have worked at it for a while. I will try to attach pics but so far can not get them to attach, thank you for any help anyone has.
