I have recently bought a Chrysler 42HB 4hp. I removed the lower unit to inspect the water pump impeller, however when I did I managed to pull the drive shaft from the lower unit. Now I cannot seem to get the drive shaft re-assembled into the lower unit and mated in the splines of the "drive gear" (thats what I call it anyhow, idk the proper terminology). The drive gear is loose and floating inside of the lower unit. I can shake it around and maneuver it somewhat into position but cannot seem to get the shaft to mate with it. Is there a trick to re-assembling this? Will I have to remove the prop shaft bearing and retainer plate? What is the thread size for the jack screws needed to remove the prop shaft retainer plate?
