Test data was arrived at after comparing a model-year 2012 Sea Ray 250 SLX with Quiet Ride and a 2012 Sea Ray 250 SLX without Quiet Ride measured at 3500 rpm, both equipped with the same power. Decibel readings will change with variances in wind strength, wind direction, current, water conditions and exact location of the decibel meter.
"Running identically-powered 250 SLX bowriders side-by-side, one with Quiet Ride and one without, I recorded a 9 decibel reduction in noise at 4,000 rpm while seated at the aft bench. That´s outstanding. Additionally, I could feel the difference in vibration. The boat without Quiet Ride produced a three-cycle per second thrum into the soles of my bare feet. Aboard the 250 SLX with Quiet Ride, I could not feel enough vibration to quantify it. Noise and vibration can be inconvenient and create a less enjoyable ride. Sea Ray Quiet Ride proves that it doesn´t have to be part of the boating experience."
