After you replace the water pump put the gear housing back on why will the flyhouse not

I just replaced my water pump kit ordered from this description. Seemed to match perfectly. . I have a 40hp tracker Mercury 2002/2003. Put everything back how it came off and re connected shift linkage but now my motor doesn’t find the neutral although throttle is in neutral. Previously anywhere in neutral I could start. Now I have to move the throttle super slow in the neutral gear back and forth in its play room while holding key turned and sometimes it starts and sometimes it’s just dead and never attempts to turn. It doesn’t attempt to crank at all till it finds a spot in the neutral while holding key turned to start. so it never cranks till finds a spot moving throttle back and forth in neutral, then it does sometimes and cranks and starts. Any ideas?

Hello. Do you have a video on how to replace the output seal on a mercury tracker 40 hp 2 stroke? I don’t have the 2 bolts to take off to pull out the prop stem.
