1986 Contessa Impeller-gctid814397

[Guest]

I have a 1986 Contessa 2850 with the Volvo-Penta 5.7L and I am trying top figure out what is the part number for the impeller for the water pump.

Also another question is did that engine come with only one carburetor or where there multiple ones sent out stock?

Thanks for any help in advance
