He will also sell you the parts if you wish to repair yourself. Ask for Brian, great people!

i contacted them , waiting for a quote?

Do you think i should repair it or just buy a new one ? Bear in my mind i am overseas and shipping both ways would cost much and it will probably cost 50% of a new unit .

Would you repair ? or get a new unit ?

Well, the supercharger is $6000.00 USD new replacement, that's a lot of shipping $$. I don't know what you are looking at to repair it, either will they completely until they take it apart.

Me, I would repair it, myself.....but that's just me. I am not afraid to take anything apart, learn how it works, and fix it. But, I can't give that advice to just anyone. There are a lot of guys that will just buy new whatever breaks, right from merc.....including engines, I am not that guy

Take it off the engine, and see if the rotors turn free with no noise, debri or damage anywhere. Not sure if the screw style blowers snow removes like a roots style, but if it does and the main blower is fine you will just be sending the snout for repair.

I am curious what caused that shaft to break? Or what exactly is broken.

This is the manufacture of your supercharger. Maybe you can find a repair manual online, and a parts source if you choose to repair in your country.
