Description
Keep your late-model Sea-Doo 300 running at full song with the WSM Supercharger Rebuild Kit for the 1630 4-Tec. This comprehensive kit is the go-to solution for owners of the current RXP-X 300, RXT-X 300, GTX 300 and GTR-X 300 who want to restore maximum boost and eliminate any hint of lag or whine.
Note that the compressor wheel is not included, so you can reuse your existing wheel or upgrade separately. The rest of the kit contains every bearing, seal, gear and gasket needed for a professional-level rebuild. Pair it with the WSM 950-112 rebuild tool for perfect results every time.
Everything included for a complete 1630 rebuild:
- High-speed ceramic bearings for reduced heat and longer life
