Pls can someone help me. I have a 1972 Cobra with an aq130d engine and 270 outdrive. The engine is out and being overhauled. Cannot get the bell housing off despite much encouragement using various tools. All bolts removed. Boat been standing for over 20 years in garage. Get one side of housing open about half inch but other side springs back. Need to remove it to get crankshaft out and get engine away for pressure testing. PLEASE HELP.
