Although your speed is just a wee bit slow the real issue is your RPMs.  You are quite shy in that department and it appears that most likely your are "plowing" due to the prop being too deep in the water.  As mentioned to you on prior posts you still have to check your set up to fully understand your prop to pad measurement.  I saw that others have suggested that you should consider moving your motor up to at least the center mounting holes.  I don't know if you did this or have performed your prop to pad measurement.  The Merc test sheet for your boat was using a black max at 19 pitch and their speed was slightly better but significantly better RPMs.  While I suspect a SS prop will help you it will not resolve any set up issues.  I would resolve that before buying another prop.
