Had a chance to run the boat again. Took a picture of the AV plate at cruise - still looks buried. With 2 people on board and 1/2 tank of gas, WOT is 43MPH at around 5700RPM. The tachometer is being a bit flaky, so I do not have 100% confidence in that number (its always something). I recently bought a used Rev 4 17p to try, but as I was about to put it on, I realized that it interferes with the trim tab, and the tab will need to be clearanced. I did not have the tools with me, so I will try the Rev 4 next time.
