Lost all my oil on a 2006 Mercury 115hp EFI

[Lavern]

I did all of the above to try and get it into reverse . When I bolted the bottom end on, there was a slight click and the bottom end slid right on.
Anyways, when I still had the bottom end off, I pulled on the shift rod and it came out approx 1/2 inch and suddenly I noticed engine oil pouring out from underneath. I lost all my engine oil. What possibly could have happened here ?

since mercury has made outboard motors from 1.5hp to 600hp ranging from single cylinder motors to 12 cylinder motors and over the past 85 plus years.

would help us to know what you are working on.

Any idea if this is a seal and I can just pop it back together ? It doesn't look like anyone else has had this issue.

This is normal....clean it up ,reinstall and change filter.

I would not call this normal. I guess that is your best advice ?

Well you have a Yamaha powerhead built for Merc and they do this as the driveshaft seals the oil pump...so yes this is my best advise .

it is possible the shift shaft was not aligned and the shaft was driven through the block. I have welded a few blocks from this

I suppose anything is possible at this point. The Lower unit was off and I had pulled the Shift shaft down approx 3/4 " and all the oil suddenly dumped onto the garage floor.

ok. Thank you Faztbullet. I am just a little leery knowing that my 15 Minute fresh synthetic oil dumped out within 30 seconds. Any u tube vids with the same engine did not do this or even mention it in the videos showing the lower unit removed and replaced, with no issues.
