Why don't you just measure it?

It's a 13 1/4 inch diameter.

Google is your friend.....

From the first hit on the Google results list:

LASER II (XR4) -- These propellers have a small diameter thru hub barrel with a 4" progressive pitch and a 30 to 33 degree parabolic rake. Used with the XR4 series and the inline motors.

Thanks guys ! I t should work well on my 6 inline 1985 merc 115.
Curious, Why do most prop sizes list as 19,21,23, were as the laser 2 props have pitch #s like 20,22 ect....

Rulers have even and odd numbers on them and we also have $1, $5, $10, $20 bills, so why not odd and even prop pitches? There is no magic in a number. Now that I'm done being a smart ***, lots of performance props are pitched at even numbers -- it's not just the manufacturer you are looking at.
