    Or they should be able to measure the prop. This isn't rocket science they should be equipped to do this easily.

    A reputable prop shop would most likely be able to identify the prop.
    Here’s a prop selection calculator.

    OK. I note you did say BII with the 7.4. Earlier post was smaller engine. See if this page makes more sense showing a larger prop of 18.25 X 19

    I can't upload the whole file for your boat but if you go to the link I sent earlier you can get the whole book on your boat and find the correct engine and outdrive combo.

    The 16 x 14 seems incorrect for a boat that size with a Bravo drive. It’s more likely a 17 1/4 x 21 or 18 1/4 x 19 or similar.
    This all is dependent on the ratio of the drive as well.
    I’d suggest looking closely at the exterior portion of the prop hub between the blades to find the part number or or the size stamped into the aluminum. Sometimes it’s hard to see. If all els fails you can take the prop to a reputable prop shop for identification.
    BTW: Mercury prop calculator has it a 17 1/4 x 21 IF it’s running a 2.0:1 final drive ratio.

    I went to the link above, and according to the US MARINE/Bayliner parts catalog the original prop was a 16 X 14. OEM part number was 34196.
