Sea-Doo GTI SE 155 Engine Rebuild (2018)

If your GTI SE 155 isn’t hitting like it used to, a full rebuild brings it back where it belongs. At REV6, we tear your engine down completely, address wear points, and rebuild it to deliver smooth, consistent power on the water.

That means stronger acceleration, better response, and an engine you can rely on every time you ride.

Built for Strong, Consistent Output

The 155 platform is known for a little more punch, so maintaining that performance matters. Because of that, we focus on internal balance, sealing surfaces, and proper tolerances throughout the build. This helps the engine deliver steady output instead of dropping off as it heats up.

In turn, you get smoother operation and reliable power across the entire RPM range.

Warranty & Support

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