"Trying to get my OMC 120hp wi

"Trying to get my OMC 120hp with a OMC 400 sterndrive to start. It has been sitting for three years and today was the first time I have tried to fire it up. I pulled the plugs and first put some automatic transmission fluid in for some lubrication. I went to turn it over and all I got was a "clunk" sound. I then put some wd-40 in it and waited a good two hours and still am getting that "clunk" sound. This is not the clicking like you get out of an automobile, this is one loud “clunk”. I know it is not the battery because I bought it this morning and have kept it on the charger so it is 100%. The propeller will turn while it is in gear also. I was going to try to turn it to see if it was seized, but there is no bolt on the front to get on. I was able to stick a screw driver in a hole on the bottom pulley and tap it a couple of times, but was unsuccessful at getting it to move. Is this a seized motor and if so what am I looking at for a replacement?"
 
"If it was fogged properly whe

"If it was fogged properly when winterized there's no need to pour anything in.
Could also be the outdrive that is seized, or the intermediate bearings.
The propeller should not turn more than about 1/3 of a revolution in gear."
