2000 mercury saltwater outboard engine problems- 200hp Help!

Hello everyone,
I have a year 2000 mercury saltwater engine that is a 200 horse that I'm having trouble with. I've had it in the water this year about 4 times but the other day I was going almost full throtle when the propeller just stopped and the engine rev'd really high. I immediately put the throttle back to idle. The motor was still running but when I would put it into gear it would just rev high. It's like it wouldn't go into gear. So after being towed in by the coast guard I had a look at it when I got back and it seems like the propeller and a bit of give to it. I could pull it out an inch or so. Should that not give at all? I am hoping it's an easy fix but that seems uncommon with boat motors, for me anyway. If anyone has any idea what's wrong it would be greatly appreciated. I was hoping to take the family out for the 4th of July but it doesn't seem like that's going to happen :-/.
Thank you,

Well, I had a look at it and there were 2 little hoses off on the side of the engine. Motor turned over first turn. Went to put it in gear and it worked! Put it in reverse and that was fine too. I didn't do anything other than put those little hoses back on. So I went to the ocean, put it in the water, started the engine and put it in gear... Nothing. I was sure that something was going to happen because I didn't really fix anything. To me, it seems like either my control box or control cables are messed up but I'm not sure. Unless it's something in the lower unit? I can't figure it out! Also, this is a year 2000 that's a saltwater series.
 
Does this look like it's on right?

The propeller nut should sit in the hex recess of the tab washer.
Remove your propeller and check the hub at the back.
Actually looking at that prop... It looks like it may be time for a new prop anyway....
 
Ya, I think it will need replacing as well. What lower units would fit on it if I found a used one? Is there certain years and hp that would fit? Thanks for the help by the way!
 
You don't know if you need a LU untill you remove the prop. The spun hub is part of the prop. Prop looks like a 14.5" X 19P.
