Make sure to disconnect the linkage for the lower unit too. If you
dont disconnect that one it'll never break free. It should be hooked
up somewhere under the powerhead.
Real PIA when I dropped the lower unit from my 175.

Other than that, make sure to remove all the bolts around the lower
unit.
There might be one there for the zinc and other by the (forgot the name
of it)
fin. (the metal piece by the zinc and above the prop)
