I just bought an X19 with the 200 SHO 2 weeks ago. Break in done. PowerTech VMX3 25pcame on boat. Best I got out of it was 63 mph @ 5600 rmp. Not a smooth ride over 60 mph. I have read enough on BBC about the Turbo FXP 25p to buy one ( $600 price ), but have not found one available. My water pressure WOT is 16ish.
You can get a Brand New Solas Scorpion prop for less than $400 on Ebay. Faster than a TXP. Just go 2 pitches, down. If your running a 25 then get a 23 Scorpion.
