Getting off the lower unit of an Johnson Sailmaster 6hp from 1986

[VJR]

Hey! I have to switch out the impeller on my Johnson Sailmaster 6 from 1986, but I am struggling with getting the lower unit off. I have removed the 2 bolts on the bottom and the long bolt at the front, passing through the extension and the lower unit. I have tried pulling very hard and managed to get the lower unit off by a small bit. I am unsure whether there is another piece that should be loosened or if I should just pull very hard (it was most likely ages since the lower unit was removed). Any tips or ideas on what to try would be helpful!

Disconnect the shift shaft coupling.

There is no shift coupling to disconnect on this motor.
