Hi, my name is Kerry

The impeller goes in the bottom part of the upper gear-case, there are 4 bolts with 3/4" heads.

Once you remove the drive and separate the upper from the lower, you remove the 4 bolts and the pump housing fom

the bottom of the upper gear-case.

I will search for a parts diagram, the site I usually use doesn't have pre-cobra parts any more.

Here is a diagram

The impeller is # *****

To seal the pump properly on re-assembly, you need Permatex #2 and you need to completely remove all

old sealant from the parts you re-use.

Let me know if you have more questions.
