Rebuild supercharger rebuild - 100 or 200 hrs?

[slaubman]

I have a 2015 Scarab 215 Impulse with twin 200hp Rotax engines. They just passed the 100 hrs mark. Searching online, I’ve seen posts saying the superchargers should be rebuilt at the 200 hrs mark but also some that suggest the threshold is 100 hrs. I’d like to get a definitive answer since, with winter not too far off here in Canada, I’ll have the rebuild done before next summer if the time is now.

Thanks in advance!

it is technically every 200 hours or 2 years, whichever comes first. my challenger (just purchased) is at 8 years on the SC which i intend to rebuilt this winter. for me personally, i will likely make it a 4 or 5 year rebuilt schedule as cost is not that high if you pull it yourself and send it for rebuilt (about $500 per SC). but only you can determine the risk/reward for yourself.

I've only seen every 200 hours.

Looks like 200 is your mark, regardless of hours. I remember being told by someone very experienced, possibly at Riva Racing, not to operate to the full maint hour interval, but say at 190, if 200 is the interval. I save a little coin and bring the super charger(s) into the dealer and let them rebuild them. That's a maint item that I definitely don't ignore.

Would you happen to have a PDF of the service Manuel for that year scarab?

I had a 2007 SeaDoo Speedster didn't rebuild mine till 100 hours and 12 years later... The superchargers on the newer ones don't need to be until 200. Mine was first 100 then every 200 there after.
