    Might help if you share what boat you're considering.

    If it's a fishing application, go with the ProXS version.

    From what i’ve read and seen it is pretty much the same motor except the new XS has a little lower gear ratio.

    Depends on the horsepower, for example 225 4s is a V6, 225 Pro XS is a V8

    Don’t forget about the extra 200 RPM, stiffer motor mounts and the low water pickups too.

    Yes it will be used in a fishing application, on a 19 ft aluminum bass boat. I knew about the higher rpm limits but did not know about stiffer motor mounts and low water pickup

    I repowered a 19 ft war eagle with a 150 4s before the pro was released. Between the extra RPM and lower gear ratio I think it makes a 2-3 MPH difference. I would have gone with the pro if it wasn’t for the wait.
