2019 seadoo rxtx 300, last summer started kicking in and out of limp mode displays U16a1, u16a2, p1550, p062c, otas fault on screen. I’m lost, doesn’t seem to be much info I can find on fixing the issue. Upgrades include worx racing Intercooler, riva intake brace and upgrade, riva through hull exhaust, riva Intercooler tubing upgrade with blowoff, riva power filter and top loader intake grate.

U16a1 and 2 are CAN (network) faults with the cluster. The first step would be to check the wiring between the cluster and the ECM. Sea-Doo uses a single twisted pair for their network wiring. Problem is even the dealerships don't have much training or knowledge on troubleshooting network faults. A lab scope is normally needed to isolate faults in the network.
