No! Some shops have a special tool that actually screws into the seal(s) to pull it out. And another tool to install the new seal. Otherwise the bearing carrier only needs to be removed to replace the seal(s).

Colton, Do you have water in your lower case oil? If so, pull the lower unit, replace all the seals (input shaft and carrier shaft) and the water pump while you have it out. Most shops have a vacuum tester to check the seals.
