i am disassembling this lower unit its a 93, and everything is out except the shaft, upper pinion gear and back gear, parts ive circled. what releases it?
Shaft should pull out. If damage has occurred, the shaft may not pull out easily. Put the shaft in a bench vice and GENTLY tap the housing away from it. Should do the trick. Care should be taken to avoid damaging the housing or buggering the shaft.
