    Sportmaster Gearcase

    How much front to back movement if any should the prop shafts have on my 2005 250XSs?

    Not sure how to properly measure but I would call it about 1/8" of movement front to back.

    This can be "technically measured" utilizing a dial indicator, and appropriate clamp device to hold it.

    Approximately 1/8" is acceptable. Excessive "end play" in the prop shaft is a sign of:

    -Improperly seated or torqued bearing carrier (or a worn bearing carrier)

    -Worn or damaged thrust washers on the reverse gear or propshaft

    -Worn or damaged bearings at the forward gear

    (A few other possibilities also exist).
