Chris and Scott, this winter did a "Top End Package" for my 540. We spoke many times prior to, and during the build. Scott bought a set of 305 AFR's, did his magic. Chris designed a solid roller that brought this package to life. They came up with an estimated power for my 540 pump-gas lake-motor build at 809 H.P. @ 6200 RPM. I am pleased to report that last weekend, I put the boat in the water and recorded , according to my EGT Sensor, max RPM, 6160 RPM. The Hi Helix impeller chart says my engine is making about 811 H.P. They missed this one by 2 H.P. Gotta give it to these guys!!!!!! Thank You Chris and Scott.
