The interval work that keeps a 300-horsepower watercraft being a watercraft — supercharger rebuilt, pump refreshed, BUDS-verified, and proven in the tank before delivery.
The owner — a League City rider whose RXT-X splits time between Clear Lake and the bay — booked the smart version of this service: by the calendar, in the winter window, before any symptoms. BUDS put the unit at 96 hours; the supercharger program's answer was now, not next season.
Teardown told the familiar story: clutch washers within spec but aging, bearings with the first whisper of play — exactly the state you want to catch. Rebuilt to current spec, and since the pump was five feet away, the wear ring and impeller got measured too. The ring was at the edge of tolerance from two seasons of sandy launches; it left with fresh clearances and the top-end speed the owner hadn't noticed slipping away.
The bay-machine extras rode along: anodes, cooling flush, connector protection — the Sea-Doo program's saltwater checklist, done while everything was open.
The scheduling lesson worth stealing: this whole job happened in January — the machine slept through it, the owner lost zero water days, and the spring launch was a first-pull start while the ramp queue behind him idled. Winter is when smart watercraft work happens; the seasonal program exists to make that automatic.
Thinking about the performance version? This same platform takes RIVA staging beautifully — rebuild time is upgrade time, and the conversation costs nothing.
Because the failure mode doesn't warn politely — supercharger components that let go feed debris through the engine, converting a scheduled rebuild into a four-figure lesson. At 96 hours the parts told us they were aging on schedule; the interval did its job precisely by being boring.
Measured, not sold: the wear ring sat at the edge of spec, and the labor overlap made rebuild-time the cheapest moment to address it. That's the combining-services math we recommend everywhere — the owner approved it from photographed measurements, not from a phone pitch.
Twenty minutes of BUDS: true hours, service flags, and fault history read straight off the ECU. Bring the machine (or book it into winterization and we'll check while it's here) and you'll know your unit's honest number instead of guessing at it.
Supercharged machine with unknown hours? One BUDS session answers it. Book the winter slot and lose zero water days.
