The first question to ask yourself re pitch and WOT speed is does the engine
reach rated rpm (or a bit more) at WOT. If not you could be overpitched,
have a fouled prop or bottom. I would doubt that the manufacurer would have
missed the pitch that bad, so look at the other two causes first. The engine
may also be a problem, but I would rule out the others first.

Don't rule out being mis-propped by the manufacturer as they might not
have gotten exactly what they ordered from their supplier. Our pretty
nearly new fixed 2 blade Michigan Wheel's blades had an inch different
pitch between them, and neither was what was marked. Balancing the prop
improved performance and greatly decreased vibration.
