Since you included,"not good for the water" i am guessing that you do not fish from a gas powered boat. If you do, would you perform the following experiment, please? Take a can of WD-40 and spray in the water and see what happens. Now start your boat motor. Do you notice the oil slick created by the exhaust? (this oil slick will be much less obvious with a 4 stroke as only the exhaust gas is contributing). Now look where you sprayed the WD-40. What do you see? Now which one is worse for the water? Neither one is what a tree hugger would call "good" for the water, but the WD-40 is, by far, the lesser of the two. So SirBob, I do not believe the manufacturer just because they print something. I have read thousands of MSDS when I painted cars for a living.
