Superchargers and outdrives
Roots Screw or Centrifugal. Which one do you think is the hardest on outdrives.

It's all in how you work the throttles. My experience with NA and making a drive last is down to pretty much 3 things within reason. 1, lower rpm going in and out of gear the easier it is on the cone clutches. 2, is getting on plane with ease without loading the engines with torque. Don't treat like a 1/4 mile drag car. 3, your re entry. Timing with getting back into the pins can be good or bad day. Just being sensible is crucial. What kind of drives/trannies. Boat length weight etc can all come into play. Sorry I didn't directly answer your question but just threw out some basics that you likely already knew but...

If that's so then I'm screwed. I'm propping for about 6,200 however won't be miles on end 8-71/548. Just here and there and to pass the locals. Yes you to E32, lol...
I've toasted a few drives however was from abuse. I don't know maybe rpm could have been a contributing factor. Who knows.

I would vote a roots supercharger is harder on the drive all other variables being equal. My opinion is based on immediate boost at all rpms where a centrifugal supercharger has to spool up. I understand centrifugal is a more efficient supercharger but if you want results without waiting roots will instantly assault your drive train. Ask me how I know! This performance sure does get expensive

Yes it does get expensive. No matter what the builds it's extremely difficult not to stab the throttles at that perfect rpm for a rush. Getting from a to b now is much more thrilling than later. I do see you logic second wind.

Ha- you won't be passing me, not with 2400 hp and twin quads.
