You can get them from various BRP dealers online. Just need the part number - which I don't have handy.
Many have bought the 'online PDF' version from Ebay for $10-$20. Not sure how these guys get away with this - but they are NOT legal copies that BRP has approved for sale.
Now, that being said, having a copy in electronic format is very handy - and CAN be done legally. Here's the deal - you can make a copy of the service manual that you own for your own personal use. That copy can be digital (scanned). You cannot share or sell that copy, or sell your original and still keep your copy. You also will have a hard time finding a place like Kinko's that will allow you to do it.
Technically, if you own the hardcopy of the manual you could buy the digital version from someone, under the idea that they just performed the 'scan' for you.
Will you ever get in trouble for owning the digital version - nope. Is it wrong to own it without paying for the hardcopy - YES. Just like copying movies, music, etc.
I bought the hard-copy for $120 online (robs performance I think). I also paid $20 and downloaded the electronic version as I was getting ready to scan it to PDF and for $20 why bother. The Ebay seller should be asking for proof that you own the hard-copy - but they don't care as they are not trying to play within the law anyway.
I guess paying the $120 for the hardcopy eases any guilt I might have about only paying $20 for something that BRP spent a TON of money on producing. Still don't feel 100% right about it--- but 99%

I know a thing or two about copyrights--- been on both ends of it. I was sued by DC comics 25 years ago for hundreds of thousands - long story--- ended up settling for much less - but now they own my soul.:yikes:
End of copyright soapbox!
