    Default Mercury props


    • Just picked up a 2002 225 EFI
      Came with 2 props.
      ​The one on it is a Mirage SS 17p
      ​The spare looks like the standard one.
      ​SS 17p but shorter and wider blades.

      I'm guessing that the guy paid a bunch of $$ and was using the Mirage that it's probably the better of the 2??

      The cavitation plate has a zinc with no fin.
      ​Again guessing the fin is missing because the bigger blades on the Mirage would hit the fin??
      ​I've seen fins that are almost thin as a pencil? might that fit on there?

      I know the fin's supposed to help the steering?
      ​I have hydraulic​ steering.
      Will that affect anything if the fin's not there?

      Thanks for the help?

    Does your craft pull to either side if you let go of wheel, the torque from the prop. will usually pull the hull to one side. The part you a referring to is a trim tab. Some Hydraulic units that have nofeedback you will not feel the pull to one side
