I think the tail has to come off mate
I have heard of people doing it in situ but wonder how when theres little room between the bush and the output shaft to get anything in
I had enough grief doing the seal with the box in the car - theyre very tight

Find split or probably better up the oil groove like Ian Oddified said...
Hammer ..
Sharp item..
Long nose pliers ..
Lots of bad language...

I did mine with the box out ..

It can be done in situ but it's not easy. Remove the oil seal (self tapping screw in through the steel part, claw hammer against the tail shaft, pull the seal out), then you need an arrow shaped bar/chissel, run along in the oil groove along the bottom and fold/crease the tail bush inwards, it will then just slide out easily with a hooked piece of wire.

Tap the new bush in carefully with a suitable tube, avoid putting a burr on the edge or the prop won't slide in afterwards and then the new oil seal.

Much easier with the tail housing removed and on the work bench though!.
