Mercruiser Alpha One Water pump Replacement Issue

[Ilockert]

So after the last trip to the lake I decided the water pump has got to be bad. So I call the local shop went and picked up the parts and came home and start tearing everything down. Well at first I thought WOW this is really easy and it was going so fast, well then I got to start putting it back together and I notice I have quite a few more O-Rings then I seen come off and notice I have more gaskets then I could use. So Now im just confused, well then I notice the lower part of the pump is what I think is the wrong part. So have a look at the images below and let me know if im just over looking something or did they sell me the wrong stuff that can not be returned?

Also if what they sold me is the wrong stuff would this kit work:

Mercruiser Complete Seawater Pump Kit/Drive Mounted

All the pictures I took can be found at:

I took quite a few.

Thank you for your help with this problem.

What's the part numbers for the kit you was given?

There are more O-rings and gaskets in the kit cause it covers different models. Just match the new parts up with what you remove and ignore the rest.

There are most likely in the new kit: new gaskets for the drain and vent plugs, and the Quad ring which seals the passage between the halves of the drive.
