It should fit from what I know. And you can get the hub replaced if there is an issue.
I have a Torque Flo hub so it is just the brass spline fitting behind nut. Looks like now it will be a Merc so I have another ?. Prop is a Tempest Plus 23. Steve blueprinted and balanced. I am getting a 2200 Champ Bay with 200 Optimax. Curious to see how that prop will run on it before I list for sale. All I know is boat has a 3 blade now. I would really like to have a 250 on the boat but maybe some day.
