New Genuine BRP Maintenance Free Supercharger 5490673 / 420893563 are the same supercharger that BRP assigns two different part numbers.
You will receive the supercharger in a box with a BRP label with the 5490673 part number.
We are a BRP jet boat dealer that is the reason for the 2 different part numbers.
This new supercharger no longer requires the scheduled 200 hour rebuild service.
