mark 55 prop

[ripping lips]

I guys new here and have got a question about a mark 55 prop its on a 1960 300m mercury. I have several props but for my boat I need to see if there is a way to press or something to get center spline push out or is there a way to do it. I have a mark 50 center in one prop that I think is the right one and want to put a mark55 center spline in. Is it possiable.? Thanks in advance. Happy fishing all.

According to my old Michigan Prop book, the Mark 55 and the 1960 300 both use the same props and the same spline(11), so why are you trying to swap hubs?

Yes I am the mark 50 uses a 14 spline and mark 55 uses 11 spline. I need the 11 spline. Thanks for your time sir. All help is appreciated.

I have a couple different props for my engine but the prop I believe I need is 25773a2 and I have it but the hub is 14 and I have extra props I can take the hub out of if possible. Right now I have a 22814a2 and engine revs a little high yet it planes out fine so I wanted to move up one prop from what the manual says. I've got all the props from the 11 pitch to the 8 pitch.
