I changed the impeller on a 3 hp 1952-54 (JW-1) Johnson. As I took it apart, the lower unit fell on the floor. Now, the driveshaft does not engage the propeller. It is pushed in all the way. Is there a key or some other magic that makes the propeller turn?

Here is the scenario I have, and I apologize in advance if this is not the correct place or format for my questions but I am new to forums like this. I have a son who loves fishing and we have been shore fishing the last few years but he is getting old enough that he wants to get out on the lakes. Good news is we live in Minnesota so plenty of lakes, bad news is I have never been around boats much. We got a 14'boat/trailer from someone and a evinrude 3hp lightwin motor. Good start they said it runs fine. We took it out a coupled times and it ran ok.  By ok I mean full throttle was still very slow, but I thought eh it's a 3hp,  I had to keep the throttle 3/4 to full for it to run. Then it started to die, right away.  I noticed a few times it revved way up for about 3 seconds, probably about where it should. But it almost left us stranded in the lake and I would like us to fix it up together but I am new to 2 cycle motors.   So far I changed plugs and emptied the gas completely to start fresh. Put it tank and it ran the same as before. Any guidance/direction would be appreciated. From reading this site sounds like a carb kit is a good start. Any suggestions? 

Motor is Evinrude 3hp lightwin model 3602e. 

I would love to be able to help teach my boy about boat motors and this one seems like a good starter project.

Take a good look at the ignition.  All and I mean ALL 3 HP motors that old need new coils, and might as well change the points and condencer while you are at it.  You cannot tell whether nor not those parts are bad by looking at them.

Check out my 3 and also 5.5 hp ignition tune-up pages.

 

I would do a full tune-up like I did before I turn my son loose with it.
