    Default Remove drive shaft

    I am returning my SE 306 lower unit. Because the motor is old, I had to buy a new drive shaft. When I installed it, I just tapped it until it clicked. Now I can't remove the drive shaft. I have tried to drive it out but it doesn't move. How do I remove the SEI drive shaft from the SEI lower unit so I can return it?

    There is a tool that clamps on to the driveshaft and then pulls the shaft out. It just has to break the clip holding it. otherwise you pretty much have to disassemble the unit to remove it.
