I have a 1996 seadoo sportster wondering if i put a new motor in it what engines would fit? Its a single engine right now. Would a newer rotax fit in it? Or is that a no go and if so where might i get a brand new motor for it

I don't think you're going to find a brand new motor. There are a couple of companies that rebuild motors. SBT and Full Bore, they both work on an exchange basis. These are short blocks, you will need to keep all of your external parts, carbs, manifolds, starter, etc.
It's probably cost prohibitive to put a larger motor in your boat, better off to sell what you have a buy a boat with larger motor or 2 motors.

Engine swaps
It is a question of money, guys put RXP motors in just about anything these days. A 787 or 951 would be a cool swap, but it would require new electronics, and different impeller pitch to make use of the new power. Even then, the pump would be a bit inefficient. I've tried searching for what you are asking about, for myself, and all I can find are comments like "just buy a newer sportster with the engine you want".
Well, I've read a thread on a 951 being installed in a x4 hull, it is a matter of one motor mount relocation, and a bit of fiberglass work to make the pump and exhaust fit. It should be easier to do on a sportster, being there is so much more room. However, it goes back to all those who blindly said "just buy a newer sportster with the engine you want", not because they have any clue, but because dollar for dollar, it is a more economical option unless you bought your current boat for a song.
If you want to "repower" with a different engine, a whole running donor ski is the only way to go. In today's market though, your looking at $2500-$3200 for a 951 ski, as is. However, you will be putting a 130hp engine, in one of seadoos lightest boats. Even though it will probably only have similar performance to the speedster of the same year, it will also have half the problems/maintenance.
If you can put an engine in yourself, and anyone can, the SBT premium 717 package is your most econical route. http://www.shopsbt.com/seadoo_jet-ski_engine_premium/P40-105.html They send you an engine, instructions, with all gaskets needed for re-installation, you put your old engine back in the box, send it back to them. They have a ridiculous 2 year no fault warranty. I've read about guys sinking skis, forgetting to put oil in them, ect, and SBT support just says "well, that's the darnedest thing, send it back and we'll send you an exchange, sorry for the inconvenience".
If you have five thumbs on each hand, this is not a good option. I've also read about sbt engines that were built on the last hour of friday. There are plenty of horror stories about "sbt explicit explicit explicit, cost me a bunch of money in labor at (insert joe-blows marina)". As suggested above, if that is the case, buy from a reputable builder, it will cost a bit more, have less warranty, but save you in labor.
Personally, I'm in the same boat as you airborne19D, literally, my engine still runs well, for now, but if I ever have to replace, I'll go with SBT, the warranty has my vote.
