I got it out of the boat without removing the heat exchanger. The flange was bolted onto 3 studs that remained in the exhaust manifold when I removed the nuts. I lost coolant when the flange was separated from the manifold. That surprised me but it appears the system was built that way. I unwrapped the heat shield and that allowed me to get a 14 mm socket with 3 inch extension unto the hidden nut. There was substantial deposit buildup at the salt water inlet and there was a rather large piece of rubber stuck in one of the elbows, that also surprised me. I really was impressed with how 50/50 ATF/acetone worked as a penetrating oil. Now to get new bits and pieces to build a new one. It really is amazing how well the engine worked considering the restrictions in the exhaust elbow.
