Scott! I have a 1980 Pre Alpha outdrive. I have changed

Customer Question

Hi scott!
I have a 1980 Pre Alpha outdrive. I have changed out the water pump reassembled the unit and now the drive shaft seems locked in place. I took off the lower unit and it will spin. The upper unit will not. I also check the top gears in the upper unit and they are good. Last note is that the unit sat for three years after I changed the water pump.
Thanks for your help.

Hi my name is Mark. What I mean it will not rotate. the good news is I got it freed up last night. it seems like the drive shaft moved in axially in the housing. hard to explain via a email. But perhaps we can explain how the shaft can shift. does there need to be a axial load on the drive shaft? Is it axial loaded when installed on the boat?MarkMark

Hi Mark. You are talking about the lower unit correct? (and not the upper)

Sorry for the delay I ran into a problem with my gambol bearing! I am talking about the upper unit. Lower unit is fine!

Hi Mark. Is the upper unit attached to the transom or is it on a workbench?
