Default Perfectpitch prop performance

I took my 28' S2 out with the new 2 bladed plastic Perfect Pitch prop
from Performance Props. My engine is the Yanmar 2gm13. At half
throttle, I got 5 kts (new bottom paint too). At full throttle, I got
6.5 kts. This seems ok.

That does sound right. Quite possibly, you're pushing against hull
speed at full power.

Any new vibrations, particularly at mid to high power?

Am trying to find the log of a cruise a couple years ago with the old
three bladed bronze prop to compare performance.

In particular, check the difference in fuel usage at the same cruising
speeds, as I've found it's easy to set the same RPMs, benefit from
increased speeds, but suffer from decreased mileage.
