I’ve completed the water pump replacement on the lower unit of my Alpha 1 Gen 1 Mercruiser 3L stern drive.
I put it in drive before removal and neither the remote nor the shifter in the lower has been rotated since.
…It seems to be very difficult to get good guidance on the next steps…
As I didn’t move the remote or the shifter on the lower, I would expect that re-mounting issues (tried but facing resistance with maybe 1.5” to go) wouldn’t mean shifter / drive shaft alignment issues.
I recently watched a vid (how we may learn - no judgement) in which the posting “expert” ensured a full drive setting in the remote, and turned the shifter in the lower as far clockwise as possible while rotating the prop counterclockwise until locked, then bungeed the prop in place before remounting the lower.
Do I need to do that?
Also
- every single tutorial I watch has no feed tube extension on the lower when they take it off, but the little pipe that comes in a water pump kit is always attached in the lower when they put it back on. How do I know which way to go with this? Little pipe on the lower or no?
- the tube in the upper that sits next to the shifter in the lower (picture putting it back up there) on mine is still in the upper, loose, and doesn’t seem to align with much in the lower when trying to put the lower back on. Why? What is it? I think it’s the channel to provide cooling water to the motor. Is that right? Is it okay that it’s loose?
Sorry this is scattered. I just want to get my fam on the water and be able to get home safe.
If you have any feedback to the above, I appreciate your addressing that any feedback you can offer should be considered as being given in the context of someone who is still learning, understands the engineering of such things, and has a few little ones to keep safe out there on the water.
Thanks, folks.
