I am trying to remove the lower unit from my 1992 yamaha 9.9 4 stroke extra long shaft(25 inch) motor.<br />how does the shift shaft disconect? This motor has the spacer to make it a 25 inch shaft. I tokk the bolts loose and seperated the lower unit from the motor but it looks like the shift shaft has some sort of rubber acordion type coupling. is this where it disconects?
