Need help identifying water circulating pump

[partgypsy]

I have a 1983 SeaRay Sedan with 2 Mercruiser 340hp 454cid Blue water engines.Possibly re-powers from the 90's
One circulating pump went bad and in looking for a replacement, I see there are different pumps to choose from. Anyone know which circulating pump to buy?
Not sea-water pump... engine coolant circulating pump.
Thanks

I take it these are inboards with transmissions and or V-drives, correct? If so are they both left hand rotation engines or LH and RH rotation?

Engine serial number please. That way we look up the exact engine and tell you the exact part required.
