Here are a few different props I've been running and testing on my 1996 Parker 2300 (23 DVCC). All testing has been performed with a full tank of fuel (155 gallons) and 3-4 people aboard but no fishing gear, ice or other heavy objects.
The Mercury Mirage was a heavily modified prop that was labelled as "19p" but I later discovered that it was actually a 20" prop. As shown in the graph (gray line), it generated the best speed:rpm ratio but provided terrible hotshot and the boat felt sluggish and heavy
Then I tested a Yamaha SWS 17" prop. From the factory, it was decent but hole shot wasn't great. I brought it to Richard Junker at Leading Edge Props in Ellenton, FL (he's amongst the best prop guys in the U.S.) and gave him the overall performance characteristics as well as a chart showing RPM vs speeds. He tweaked it a bunch and I tested again. Slightly faster but much better overall handling.
Then I decided to install a Permatrim in an effort to get the bow down (Parkers always ride bow-high). This last modification gave the best performance and really makes the Parker 2300 feel like a different boat. Two things are MOST noticeable ..... first, you get on plane almost instantly. Very quick to get on plane and very little bow rise during this transition from hull-speed to planning speed. Second, the entire boat rides higher out of the water. Previous to the Permatrim install, water would "break" from the hull 1/2 the length back from the bow ..... now it breaks 2/3 back.
As Jim has posted before, the 23ft boat now feels like a 25-26ft boat.
Anyway ..... here is the graphics. If anyone wants the raw numbers, I can try to post them too.
