Old Merc Tower of Power 115 Issues

Just picked up a nice little speedboat with an old Merc 115 Tower of Power on the back, I have a couple of issues regarding whats normal for this type of engine. Note: I don't know the year of this engine, but I'm assuming it's aged anywhere from 1975-1982.

1. When I put the motor into gear, I hear this clicking/grinding noise for about three seconds before it catches and the clicking stops. Is this normal?

2. The previous owner just had a brand new prop put onto the leg, but the prop, even after being fully tightened, seems to have some play side to side, as in I can wiggle it side to side. Also, when I push the prop against the leg, there seems to be a spring compression system that allows the prop to move forward about a quarter inch and spring back when I let go. Is this normal?

Any info is greatly appreciated!
