I took the lower unit (88 Aplpha one) Off the wellcraft 2 replace the water pump and having a hell of a time getting her back on. It seems that i cant get the shaft to line up inside. Given this is probally a 2 man job and and im in the back yard myself laying on the grond trying to lift and turn the prop and so on. She wont slide up that last 3/4 of a inch. any easy way to do this? I really would like to be on the water sat than laying on the ground
