This might be a dumb question but, what prop is on my boat? pitch, splined or not..... the manual is useless.

I have a 2003 x2 with mcx.

Thanks

Look on the hub between the blades, it may be stamped on it! Prop manufacturer and Pitch/Diameter and mfg. date. Some info may be on the hub face against the prop nut.
Is it a 3 blade or 4 blade?
Is it gold/brown color [nibral]or silver/chrome color [S/S]?
Should be 1 1/8" shaft with the 1.56:1 transmission.
Take the cotter pin out of the prop nut and shaft, remove the nut and look to see if the two mating surfaces of the prop and shaft are smooth [tappered shaft/prop] or if it has notches all around the shaft and prop hub [splined]. Also look for info there.

O.K. I just looked closer it was stamped behind the nut.It says

OJ 14,18 CUP

I'm assuming 14 is the Dia and 18 is the pitch it is a splined shaft.I'm also assuming this is a left handed rotation.

Also between the blades there is the words...OJ Johnson 503.

Your boat came with a OJ cast Nibral 14x18 prop with a 1 1/8 inch splined shaft. It's a 4 blade. The only transmission that came in that boat was a Hurth V-drive 1.5:1. I don't believe you have a cotter pin, just a nylon locking nut.

Looking at the manual it is an 1-1/8" splined shaft, 14x18.
