What real life speeds are people getting with the 575's in the 36? Is anyone using the Arizona Speed pully and ecu upgrade and if so how much did that improve performance. Lastly, has anyone done the Superchiller upgrade and what improvements did you see also. Thanks

in stock form the 575 boats usually ran in the 118-120 range. there were a couple that ran better, but thats about the norm.

I use the Arizona kit. Like Obrien said: 118-120 GPS with 1.35 ratio, 36P bravo props, 5600-5700 rpms, sometimes on limiter, and sportmasters, no intercooler. It is a minor upgrade, but helps a little.

Jason What R U Doing Now

throw the intercooler in there with the pulley swap, and the boat should get to the upper 120s.

The 575's usually ran 122 in cold weather and 113 when it got hot. The propellers were 34 Bravo's with the diffuser cut off.
