Does anyone make a coolant reservoir cover for a 525efi?

My reservoir has yellowed and looks like crap.

I know Mercury makes a carbon fiber cover but its like $650, way to much for me.

Thanks

I was going to say the Merc carbon one is nice but as you see it costs as much as it is pretty. I do have a pair of Hardin aluminum reservoirs from my 525's I am going te sell. Not 100% sure they will work with the stock headers though. PM me if you are interested. They are painted to match Merc blue.
