[salmon07]

hello every one I am new here so any help will be great I have recently got a rxt 215 year 2006 127 hrs when I got it it had 99 hrs on it so I had the supercharger rebuilt also replaced the battery have been out on it on a few times but yesterday when I got home took off seat to check the battery I noticed that the polystyrene block inside the hull on the port side has melted about halfway along it I have posted some images so you can see where it has melted any one got any idea thanks

Well if harsh cleaners were sprayed on the foam it could have caused the melting.

there was no cleaning agents used inside the hull I can see where your coming from thanks for the reply

The only other thing that would cause it to melt would be heat, maybe your exhaust water line is partially restricted causing excessive heat in the hull, try flushing the system out really well

you say exhaust water line can u explain a bit more

gasoline will melt styrene in a heart-beat. Did you use gas to clean anything in that area?

Your Seadoo needs fresh water to cool the exhaust, the black line that goes to the exhaust manifold of just one of the water lines I was referring to that cools the system, I'm not sure if you do or not but its possible something is restricting the system slightly causing it to run hotter than normal in turn melting the polystyrene in your hull

Judging by the dark residue on the hull i'd say Your Jpipe is either cracked at the flex area or your V clamp is loose.
