85MPH in the HEAT! 2025 Sea-Doo RXT-X 325 Gets a Calas Cam & Custom Tune

​We saved this one just in time! 🚨 This 2025 Sea-Doo RXT-X 325 came into the shop running terribly thanks to a sketchy eBay tune. The customer was convinced the engine was completely hurt, but we knew exactly what this ski needed to get back on the water and dominating.

​In this episode of Calas World, Ernesto Calas tears into the engine to do things right. We ditch the bad tune and install the very own Calas Cam, complete with Calas springs and retainers, plus a brand new prop to put the power to the water.

​To dial it all in, Chris Caputo Junior works his magic with a custom tune using HP Tuners. The result? We took it out in the middle of the day in brutal heat and hot water, and STILL ripped 85 MPH! 🤯 With colder water and cooler air temps, this exact setup is easily going to push nearly 90 MPH.

​🔧 What we installed in this episode:

​Calas Cam

​Calas Valve Springs & Retainers

​Upgraded Performance Prop

​Custom HP Tuners Calibration by Chris Caputo Jr.
