Mercruiser 5.7l carb, audible alarm test does not sound on key on unless the trim up/down button is pressed. Once pushed, alarm test sounds. Any easy areas to check wiring for this specific issue?

2014 Carb.
Read the title but a 14 carb, that just makes me say wow

So your issue is you want to hear the alarm when the key is turned ON?
If you turn the key ON and don't start, the alarm stays OFF?

Boat is a 98 Baja, engine was replaced in 2014. The alarm test when turning the key on but not starting does not work until hitting the trim button.

Ok a 98 with carb that's better
If you turn the key ON and do not start for 5 minutes does it turn ON?
