Sea-Doo Challenger 1800 Jet Boat Engine Rebuild (2006)

Older Sea-Doo boats like the Challenger 1800 are built to last—but over time, engine wear starts to show up. When that happens, a full rebuild is the right way to bring it back. At REV6, we tear your engine down completely, correct problem areas, and rebuild it for steady, dependable performance.

That way, you’re not chasing issues—you’re running an engine you can trust every time you hit the water.

Built to Extend Engine Life

With older platforms like the Challenger 1800, the goal isn’t just power—it’s reliability over time. Because of that, we focus on sealing surfaces, internal wear points, and proper tolerances throughout the build. This helps prevent repeat issues and keeps the engine running consistently.

As a result, you get smoother operation and a setup that holds up season after season.

Warranty & Support

Every engine includes a 1-year warranty, with the option to upgrade to a 2-year no-fault plan for added protection.
