    Merucry 4 stroke Prop Help

    Looking to get a spare prop for my Mercury 250 HP 4 stroke on a 2020 Ranger Z521L. Not sure if it’s a 1 or a 1.25. Serial number is 2B743265. Looking for a Tempest 23P.

    The prop will not be different-just the hub.

    Well, I found out mine was 1.25 when i tried t use the hubs i had from my older Optimax. Would not fit. Your existing hub will work.

    Definitely 1.25" on that serial number.
