I cannot figure out how to put the lower unit back to the motor after I
have removed the lower-unit to check the impeller. I inserted the
drive-shaft back to the hole and lined up the bolt; but I could not put
the lower unit all the way; something got stuck, and I ended up getting
a 1" gap that I could not close. I kept rotating the drive shaft
hoping that this might help the driveshaft to get on gear; but that
didn't help. At one point, I managed to get the gap to close to 1/2"
after spinning the driveshaft; but subsequent attempts of spinning the
driveshaft didn't help. By the way, the gear was at neutral if this
matters.

Am I missing something?

Thanks in advance for any help.

Shift shaft and water-pipe need to all line up too.

I forgot to check the shift-shaft. I re-read the SELOC repair manual,
and indeed it mentions about the shift shafe in relation to installing
the lower unit. Unfortunately, it doesn't say where it is and how to
adjust it. I think I will have to order a service manual from Mercury
to know exactly where everything is. Thanks for the pointer.

1- if you check the impeller-replace it!
2- service manual should show you what to line up.

Yes, I intended to replace the impeller and the gaskets. But then I
encountered some problem and needed to put this off for a while, and I
need to put the lower-unit back to the way it was. I probably need to
replace it soon or in next spring when I bring the motor to a mechanic.

I will need to order a service manual from Mercury. I cannot find the
necessary info from the repair manual by SELOC. Thanks for the
suggestion.

I finally figure out why I could not get the lower unit all the way up
to meet the rest of the outboard. I forgot to do two things: (1) Push
the shift to forward (2) I need to wiggle the shift shaft a bit to get
it to line up to the shift-shaft-coupler.

Now, I have mounted the lower unit back to the motor.

Thanks.
