London, welcome! That motor has what we call in this club a "five bolt lower unit". You probably noticed one bolt is bigger than the rest. 3/8 goes in from the top and the 1/4’s go in from the bottom. Here is what I do. Find a longer 3/8 bolt, might take a road trip! Cut the head off with a hacksaw. Screw it into the gear case and it will serve as a guide when assembling the two cases together. Also will hold it in position when you align the shift rod and the water tube. Make everybody happy!
