1970 25hp Not pump

[Carryion]

I picked up a 1970 25r70c and put in a new water pump. Flush the eng and it will not pump water! I can hook a drill to the main rod and it will pump water. But when it running and all connected it will not pump water any idea what Im doing wrong?

Put more water in your test bucket and about 7"above the impeller.

I have all the way up to the shifting Connect hole That like 5 inc above the water pump. No Boat repair shop here 80 mile 1 way to closes! Should not be that hard to figer out but Im stump. Ill take off the bottom end again double check its pumping!
