Why Replace the Supercharger?

The supercharger is subjected to extreme rotational speeds and high temperatures. Bearings, impellers, and internal seals gradually wear out, especially in the absence of regular engine oil maintenance. Supercharger failure can lead to a complete loss of power, or even serious engine damage.

  • Progressive or sudden power loss
  • Abnormal noise (whistling, grinding) from the supercharger
  • Unusual vibrations at high RPM
  • Preventive inspection after 100 hours of navigation or every season
  • Replacement or reconstruction every 200 hours

It is strongly recommended to replace the supercharger at the first signs of failure and to strictly adhere to BRP's recommended oil change intervals to preserve the supercharger's lifespan.
