I bought a used 23P Mirage Plus prop. The # is 48-13704. It is off a 2002 Baja with a Bravo outdrive and a 496. I want to put it on my 89 454 with Bravo I outdrive. It has a larger diameter hole in it with 4 splines. My outdrive has a smaller diameter shaft with 15 splines. What do I need a hub or adapter? Could someone help me out with a part # or place to buy? Thanks and sorry for the dumb question.

You need a flo-torque hub kit.No big deal take your prop to a Mercruiser dealer,show em what you got and they will fix you up.Can't remember what they cost,not real expensive.

He probably had an XR drive on it. Like said above the hub kit is only around $50 or $90 for high HP hub kit. I just bought one a couple weeks ago. No bid deal.
