04 FE450 Water pump impeller shredded,

Hi everyone.
I am new here as I have recently purchased my first Husaberg, and am loving every minute of it....
Well, I took a bit of a spill in all my exuberation. I hit water the pump intake tube on a rock. Promptly my coolant started spraying out. After 5 seconds of stupidly watching my coolant spray out. I decided this wasn't good as I was a couple of miles away from home in the mountains, (off road). I had just put Gorilla tape on the split out seam in the seat. Instant patch. And yes it stuck to it while wet. I won't say it was perfect, still only a drip. I made it back to the cow watering pond and after filling the radiator with my goggles because I didn't have anything else.... (Well I wasn't really going on a ride...just going for a few minutes.) I made it home. No boil overs, and no problem. Yea for Gorilla tape
So I pulled the hose off when I got home. broken water pump cover inlet. Just the barb piece that holds the hose on. I pull the water pump cover, The Impeller is toast, all the fins are gone. Now the piece of metal that broke off was only
maybe 2 or 3 mm x 15mm maybe.
I then back flushed the engine and radiator with a garden hose backwards from the water pump hose to see if I could get the pieces out. I could not, nothing came out at all.
Is there any other way to get the pieces out? Where are they likely to be? Will they likely plug up the radiator, or are they likely sitting in the block somewhere? Should it be worried about it?
Where Do I get a new impeller? Does someone make performance aftermarket impellers and housings.

Thanks for any opinions in advance

No aftermarket parts. Any dealer should be able to get you the parts. If you flushed everything out as best as possible, I think you will be OK. Be sure to bleed the cooling system when you refill it (there is a bleed screw on the head). Do not overfill the radiator, only fill it about 10mm over the top of the core.

Thanks for the reply.
Any idea on how to get an impeller with no fins off of the shaft. (I am assuming it should slide off after the retaining clip is removed.) There is nothing to grab!

Gently pry up with a suitable tool (screw driver). you can try grabbing it with a pair of vice grips. The impeller is keyed to the shaft, you have to come straight up with it. The fit is just snug, it should not be to hard to come off.

There is a new housing on ebay right now.
