550 front cover/bumper?

[whennotsailing]

I have an 84 js550, I see the 550sx's had a rubber cover/bumper over the front and I want one for my ski. Are those still availabe new? Can someone point me to a place online where I can get one?

Also, a real newb question, what is the difference between a js550 and a 550sx?

Thanks.

The SX bumper cover is available new for about fifty bucks through an OEM parts dealer.

The JS550 was introduced in 1982 and the 550SX in 1990. With the SX came rear exhaust and reed motor. I'm not sure of other differences.
