mr alpha with sierra bottom end oil coming out of hole

[skinny1965]

ok so i did a water pump replacement on my out drive. and once all done and went to fill it with oil and it started to come out of hole . an anyone point me to what to look for when I pull this apart should i remove the upper and lower from the boat to look aat or just remove the sierra bottom end to look

Easiest to remove the complete unit and set in in the stand. If it didnt leak before you did the work and now does , drop the lower and check your work.
You did install the small flat O ring between the units, correct?

ok so I am missing something i still have air leak if I test with low pressure air.
now let me say this it is a mr upper and a sierra bottom end
when i got the new pump kit and base plate got home and put what I thought to be right o ring on base and installed it (seems sloppy now i look again) when i was done installing the water pump i had left over gaskets and o rings ( I figured kinda universal kit) but now with troublesi wounder if I missed a bunch of stuff
will have to find a blow up of pump assembly

or looking for any other suggestions

Did you verify the quad ring that goes between the upper and lower?

ok got it figured after several removals and looking and looking
turns out the marina sold me the wrong pump base so it didn't seal
