The hydraulic steering and tie bars on the transom was also black from the exhaust blowing on it.

Are the rebuilds just on your carbs or were the engines done also? If the engines sat for that long you need to do a compression test or crankcase vacuum check to see if the piston rings are still sealing. Anything you do to the carbs will be a waste of time if the engines arent healthy. Pumping oil out the tailpipes looks same as an overly rich condition.
