I'm showing a 9.9 inch diameter with a 9 inch pitch for a 25 horse mercury. Yes, 10 spline.

Why can't they just write that on the side instead of using code like it's a big secret?

Its actually for a Nissan but I figure they are the same.

I dug a little deeper and you are correct. Honda, Nissan, Tohatsu, and Mercury all use the same size 10 spline prop shaft on some 25 HP models.
