Working on a 96 johnson 88hp spl v4. I am trying to remove the lower unit. I have completely disconnected the shift rod under the carb. I removed the 4 large main bolts on the upper edge of the lower unit (2 on each side), and the large bolt on the under side of the lower unit. I removed the trim tab and the hidden bolt. I cannot find anymore bolts or any reason why this thing won't drop. It was last taken apart 5 years ago to replace impeller. please help if you can, I have to get this off tonight so that I can be at boat shop to exchange before noon tomorrow when they close, and it's a 2 hour drive.
