I have a zt280 I just bought that came with a 23 mirage plus. It has a 496ho and I'm hitting the rev limiter at 67.22 mph GPS. I want to go with a four blade. Has anyone tried a hydromotive quad iv x on a zt280? I'm considering this or a bravo one prop.

I don't have any experience with the zt280 hull, but you might want to join the checkmate forums. You'll get more foot traffic over there and hopefully get your question answered.

I ran both on my 270 and the bravo ran much better for me.

67 is pretty good. My ZT280 has a 502 MPI.415hp. I can only get 64 on GPS. With the same prop your running.

I got 68gps with a bravo
