Both engines were trashed. We were able to rotate the port motor but the starboard counter-rotating engine was seized up. Mostly because of moisture from the rusted exhaust riser seeping back into the cylinders. We used a standard engine life int eh cabin then a forklift/jib to pull the engines out. For the sake of safety we reinforced the floor with 2x4s to support the weight of the engine. The make things easier, we removed the manifolds and the cylinder heads on one of the engines.
