sea doo lrv

I got a 2001 Sea-Doo LRV from my father in law. It's been sitting under a shed for about 6 years or so. We cleaned the carburetors and hooked the water hose to it and got it cranked. When it cranked some black plastic that looks like some sort of liner came out of the impeller. Does anyone know...

I bought a 2000 lrv with 10 hours on it. like new condition, I want to put a fish/depth finder on it. anyone have a setup or pictures of such. also any fishing set ups would be appreciated.
