We are now able to tune the full range of Sea Doo Jet Skis running the Bosch MED17.8.5 and Siemens MSE3.7 ECU’s which are fitted to the 1.5 Rotax engines in both normally aspirated and supercharged formats. 

We are able to do full Sea Doo performance tuning as well as remove the speed limiter (most of which are 65mph) and also increase the engines RPM band. Celtic Tuning’s Sea Doo Tuning will improve the performance of your Jet Ski giving it the ultimate performance.

With the 1.5 Rotax engine being the basis of the Sea Doo Supercharged engine range, we can provide software to match any hardware upgrades including the supercharger for even more power.

A Celtic Tuning Sea Doo Remap can make days on the water even more fun! - See more at:
