Is the TRS shaft the same size and spline count as a Bravo or XR?

I have a customer wanting a prop and he doesnt know. I dont have a TRS to check.

Thanks!

Yes, we had TRS' on my Scarab and had some cleavers off the boat i didnt use....sold them to a guy with Bravos after testing and they fit no problem. They may or may not need those bronze spacer washers between the prop and drive in some cases....
