As header, I have a Mercury Vengeance prop. Good condition, couple of marks to leading edges but nothing at all serious. Came off a Mercury 2004 200HP V6 but I assume that similar powered models have the same splines? But please check if you are unsure it will fit your motor

Which I guess makes it the 23 pitch version.
