Sea-Doo 230 SP Tower 520 Jet Boat Engine Rebuild (2012)

The 520 platform is built to move weight and hold power—but when the engine starts slipping, you feel it right away. At REV6, we rebuild your Sea-Doo 230 SP Tower 520 engine from the inside out, correcting wear and restoring the strength it needs to perform under load.

So instead of inconsistent output or fading performance, you get an engine that stays steady and responsive every time you run it.

Built for Heavier Loads

Engines in the 520 setup see more demand, especially when running passengers, gear, or towing. Because of that, we focus on internal balance, sealing, and durability throughout the build. This helps the engine maintain consistent output instead of dropping power under stress.

In turn, you get smoother operation and reliable performance when the engine is working hardest.

Warranty & Support

Every engine includes a 1-year warranty. In addition, you can upgrade to a 2-year no-fault plan for added protection.
