Hello all

I am repowering this winter. The new engine is a generic marinized GM, not mercruiser. It has been built to specs basically identical to the 454 mag, so I am basically using a parts guide for that motor to furnish the sea water pump, alternator, and power steering.

For the sea water pump, I do not want to use the decrepit garbage from the old motor but rather a nice brass and stainless jabsco unit.

My retailer lists a jabsco pump #43210-0001 as a direct mercruiser replacement for 46-72774-a32. However, stemtostern.com lists as a 454 mag water pump as 46-807151A12 .

What is the difference here? Mounting brackets? Pulley bolt patterns? Flow? Anything at all? If jabsco makes a water pump for me, what part number is it?

(also i get a sweet discount on jabsco parts from a friend)

THanks,
Mike.
