125Hp Force Water pump imp Install???

Well hopefully someone will be able to clue me in as I think I got myself into a heap of crap Lol. I will start by saying I stripped down my Bayliner to re paint and seck it. While the motor was off I decided to replace the water pump impeller. I made sure the motor was in neutral when I removed the Linkage cables then while removing the lower end I nived the linkage while pulling the rod out.. I know dumb then to top it off I pulled the rod out of the lower unit too. My question is if anyone can tell me what I will have to do to get it all back together. I might have to go pick up a service manual as I do not have one. The funniest part is I work on motorcycles and cars alot which is why I cant believe I got myself into this mess. The rod connects at the top whit a roll pin and a  cotter pin and at the bottom there is a hook like cam I am  not sure how that came off.....HELP ARE THERE ANY FORCE MECHANICS OUT THERE...Lol

Sorry about the long read I appreciate any help I can get tremendously
