I have one of the last straight bottom 2000 TG's built w/ 500efi's and bravos. Im running bravo 1's now and picked up a used set of HydromotiveQ-4's to try. I thought they might help the ride, being more of stern lifting prop compared to bravos 1's.

From my experience in my straight bottom tiger with 500Efi's( but pumped up now) straight bottoms don't like stern lift, they need bow lift to run flat and no porpoise. I also turned mine in and it runs much, much better. hope this helps.
