We recently purchased a Black Thunder with 750 Cobras and #3 drives. When we went to look at the boat the props were on it but nicked up. The dealer sent the props out to be reconditioned by Mercury. The problem I have is I'm not sure if I got the right set of props back. Since I did not take notice of the size prop before hand I don't know if I have the right set for this season. When the boat was delivered they sent one set 17 1/4 x 32 but later swapped them for another set I was told was the right set 17 1/4 x 27.
Any help in possibly choosing the correct prop would be much appreciated.

Thanks,
Bill
