Can a VHF radio "intercom" circuit power a hailer bullhorn?

Our new-to-us boat came equipped with an old "concrete block" vhf radio that works as a radio but lacks many modern features. One of the features it has is a Hail function but it doesn't work; no sound comes out of the hailer bullhorn.

We have a second VHF radio, much more modern, that does not have a Hail button but it does have a button for Intercom. According to the manual, the Intercom function allows using the mic to broadcast to people over speakers in other parts of the boat (like the salon). That Intercom circuit isn't currently hooked up to anything.

Is there any reason why the Intercom output couldn't or shouldn't be hooked up to an external PA/Hailer bullhorn-style speaker? Would there be enough wattage to make it work? Or are there hailer bullhorn speakers that need very little wattage?

You can make it work, if there isn't enough power to drive a hailer, there are I believe amplified ones, that of course would require power.
However if you newer radio isn't DSC, I wouldn't bother, I'd replace it.
