Re: lower unit probs
First thing be patient when changing a lower......can be expensive. You have three parts to line: shift shaft, drive shaft, water pump and if that isn't enough you have the alignment of the lower. Place your shifter in forward before beginning. Place your lower in forward as well. Your drive shaft well be the first to align, turn flywheel counter clockwise until it slides up.
Your shift shaft should move around enough for application, then your water pump pipe. Its nice to have two people when changing lowers...comes in handy...Blazer
