After some experimentation, we were able to retrofit a 2025 Seadoo 10.25 inch gauge from the upcoming 2025 GTX Limited onto a 2020 and 2022 RXTX.
We are still working out the kinks in the system, as this gauge was not meant to be installed on the Bosch ECU, but rather on the new Bosch MG1 ECU. The gauge is pretty much plug and play on 2024+ Seadoos, but requires a little bit of engineering to get it to work on 2023 and older machines.
Along with the larger cluster, you also have to replace the handlebars with all the buttons.
