Re: Water pump issues ...
 

Looks like for 97 5.7 doesn't matter , pump # is all the same , injected or carbed.
Part#46-807151A9 is what I come up with for the pump assembly on all versions.
Really need to have the # from yours to make damn sure though.:)

Re: Water pump issues ...
 

Yep ... That's the same # as is on my pump minus the " a9 " so that's probably the replacement pump. I saw a stainless steel pump some where on line for pretty much the same price , but now I can't find it ...? Lol.

Any idea where on the motor I can find the identification number / ID ....? Every time I look something up it always ask for the motor ID number .... I don't see it on the motor any where. ???

Re: Water pump issues ...
 

Use the drive # for reference. Long as you know the motor hasn't been changed , it will work for your ID # :)

Got the stainless steel water pump for less than the oem pump from mercrusier ... Looks like it'll last for ever ! I'm happy.

Also one of my Mariah decals on the Side of my boat some how came off , I contacted the person on our site here to get more ,,, but still haven't heard from him , ... So I ordered a pair off eBay . Got them yesterday . They are pretty much a prefect match ,,,,
