I installed a New Johnson Pump 10-24915-01 on my 95 454 bravo merc so that I could remove the merc unit. After I started the motor the pump moves a lot during 800rpm. It doesn't move like the shaft is bent Mind you that I had this motor out and took my time cleaning the mating surface on the pulley to ensure a flat fit. There is no way to center the pump exactly to the pulley due to oversize holes on the pump assembly. I don't want to ruin the pump or destroy my main bearings. Is this normal or is there a better way to center these style of pumps?

Do you have the support bracket installed holding the pump housing?

the holes align to pulley and yes I have the stability arm attached. The holes are just .030" larger than the bolts. I was looking at machine a bullet but I can't imagine I should have to.
