Do you know before/after speeds, and just as importantly fuel consumption?

Beautiful boat, and love the drives!

Sweet rig.

Yea, they are fighting the water pressure of 45-50 psi. I try to explain these things but "lost in translation" is more than a movie.

Before the boat as naturally aspirated 525's and they had Bravo issues. The owner wanted more speed as he had read the 700 package that Cig was building produced 100 mph so he wanted something similar but no Bravo's.

With 525's and 32P labbed Maximus it reached 85 mph @ 5200 rpm. It ran 84 mph with a 32P Bravo One at 5,400.

Prior to blowing off the water hoses the boat hit 104 with more to go. Owner is really happy and will be more so when he gets the water pressure under control.

Cool.

Any estimates on what the gain is w/ just the drives, both in speed and fuel savings? Too bad he didn't do this in stages to see the results more clearly.

?? Honestly, the boats typically pick up 10+ in the mid range and 10+ on the top end. The customer wanted the blowers as it looks like the new 39' Top Guns but has Arnesons instead of NXT's.

Fuel?

Yep, same kit for all. TRS conversions allow the engine to come rearward like it would for a Bravo install.

Probably an honest 720ish
