I wouldnt start it again until you get oil up on top of the heads, is this an MPI motor ?.....pull the the dist. get a priming shaft tool and a 1/2 drill and see if you can get the oil to move, there may be an air pocket in the pickup oil pump causing it to cavitate. pickup to close to the pan ?

Normally the new oil pump comes with the pickup attached, your old one should have been the same way.
Here is the one that should have been in the motor
Genuine Mercury & Mercruiser parts. 827643 PUMP ASSY-OIL Genuine OEM Mercury Marine-Mercruiser part
Others do make a good point that maybe a rocker nut is coming loose or a stud is starting to extract.
It is just a light ticking correct?
