MerCruiser alpha one v8 can some help me identify where this noise is coming from

gimbal bearings die form water intrusion and the same water gets into the U joints too. A exploding U joint at 4400 rpm is like a small grenade . The whipping action of the center section can destroy the transom housing or create a bigger leak than your bilge pump can handle.
A $6.00 gasket is a whole lot cheaper
 
I think the growling gimbal bearing was masking the lifter tick. Only now with the drive removed can you hear the lifter. As light as it is I would not worry unless it gets a lot louder
