My '75 cobalt was cruising fine, for a little while, then something give. The balldrive shaft in the intermediate housing has broke or a bearing has give. The assembly is loose in the housing. I am waiting delivery of an omc manual, but would like to go ahead and remove the outdrive. I can see the elec. shift wires that run thru the intermediatre housing into the lower unit. Is there a discconect somewhere to allow the removal of the outdrive? Thanks
