Johnson 115 hp prop ??

[goblerblaster]

I have an OMC Raker stainless prop on my Seaark zx180 -18.5 foot Aluminum bass boat- that got nicked up bad. I have found Rapture Stainless prop on ebay that I think will fit.. However I can't find a part number, diameter and pitch number, or anything but thr name " raker" stamped on the outside of my existing prop. I even took it off and can't find any numbers inside the hub. I really like the performance of the current prop and don't want to buy a new one that is the wrong pitch.

Any ideas on where I can find the numbers I need on my current prop? By the way, the motor is a 2001 Johnson 115 HP

My Raker has the part number and size / pitch embossed on the inner hub in the area where the nut and washer hold it on.
