Sea-Doo Supercharger Rebuild

Send us your supercharger and we'll rebuild it with all-new OEM Sea-Doo parts, then send it back to you. Turnaround is quick, usually the same day. Sea-Doo recommends a rebuild every 100 hours or every two years, whichever comes first.

​

Removal and refitting instructions are available on request. Need the special Torx tool? Just ask and we'll post it to you first class at no extra charge.

​

Why rebuild? Three reasons. Bearings: the impeller spins at up to 45,000 rpm, and the bearings are rated for 2 years or 100 hours. Washers: as the clutch wears, extra friction and heat can cause a catastrophic washer failure. Performance: a slipping clutch stops the supercharger making full boost, robbing your engine of power.

​

NEW: Sea-Doo 300 Supercharger Overhaul

The 300 hp supercharger fitted to the 1630 ACE (RXP-X 300, RXT-X 300, GTX Limited 300 and GTR-X 300) isn't rebuildable according to the Sea-Doo service manual. The manual gives a clutch slippage specification, and if your supercharger is out of spec, the official answer is a new one at around £1,500. We can usually save you that.

​

What we can do for your 300 supercharger​

• Clutch slippage adjustment – we reset the slippage to bring an older supercharger's boost back and help prevent supercharger clutch failure.

• Shaft bearing replacement – a cost-effective way to give your supercharger more service life.

• Individual components – we can supply separate supercharger parts, not just a complete unit.

• Your choice of parts – genuine OEM parts as always, or high-quality, proven aftermarket components from manufacturers we deal with directly, for a more cost-effective repair.

​

If your supercharger turns out to be non-serviceable, we keep new 300 superchargers on the shelf, so there's no waiting for parts. And if you decide not to go ahead with the repair, we'll return your supercharger to you.
