Based on new owner maintenance recommendations from the forum, I plan on taking props to Holland Propellers, Holland Michigan, for a free scan. A short discussion with one of the techs prompt many questions regarding the boats performance. Below are the questions asked by the tech:

What prop is currently on boat?
I gave him the bill of material description, but I honestly don't know for sure.

What is the WOT rpms?
I indicated the short time I operated the vessel I got up to 4400 rpms

What speed was achieved at WOT?
With wind 32-34 mph

How responsive is handling at idle?
Good with little and no currant, need more toddle with wind and I imagine currant? He seemed to zero in on the boats responsiveness at idle, 800-850 rpms.

Questions went on regarding props closest measurements to hull, strut, and rudder.

He then asked if I know of the new technologies in propeller engineering? My answer was no but I understand things evolve.

So what am I getting into?
What should I expect taking in 20 year old props?
What should I be getting with the above performance questions?

Any help from the group will make me more prepared for the visit. I really don't want to walk out of there with new props if it is not necessary. I also do know enough to make judgement on pitch changes to help at idle.
