The new motor (25 hp mercury) doesn't get her up as fast last as the older
engine. It is entirely possible that the pitch of the "standard" prop is not
sufficient to give me a "hole shot" that the older one did.///

Let's raise the issue up from a level of "entirely possible"
by reading both the old and new prop data, and sharing the numbers
with us.

It is usually cast into the hub area of the prop.
If no numbers show up, The diameter is easy to measure,
the pitch not so easy, but reading the angle of a blade at the same
point on both props would give a clue, even if no numbers are to be
found.

Either too high or too low a pitch can make for slow lift onto the
plane.
