Be nice to know what it is.
Wouldn't wan't it on me motor, but soaked in to me leaf springs might be good.

But on the other hand if it's not greasy then it's the white paint going yellow, even your white gel coat on your glass boat will do that.

So go out and by some white paint to re-coat her.

Could also be vege oil. It will leave a yellowy coating behind that sets like thick glue.
