Removing a water pump from a Rover V8?

[300bhp/ton]

Trying to take the water pump off my TR7 V8. Not sure if I'm just being dumb or it's just being stubborn.

I've removed all the bolts I can see/feel. Yet I can't get the pump to detach. Any tips or have I missed something?

Thanks.

bolt behind the pulley itself ?

Think there can be one hidden from view a bit. They can seize on as well.
