Salt away is AWSOME, however I agree with the rest of the comments, the vigorous flushes are more than enough. Look, about once a year, I actually take apart my engines just to lube EVERYTHING & I mean EVERYTHING in it & when I open them up I never have any corrosion nor do I have any of that white powdery shit I've seen in other skiis (Like my first jet ski). I run my waverunners for 20 minutes on the hose after I get back from the water, then do the famous dry revs for about 15 seconds so it spits most of the water back out. Also, letting your waverunner sit without cranking at least once every 15 days is not too healthy. I recommend you crank it up atleast every 2 weeks. That's the way I do it & 'till this day, it hasn't failed me. Oh, & by the way, I live in MIAMI & I ride in the FLORIDA KEYS! So fresh water is not too much of an option for me in the summer. CRC is great for the exterior of your engine. Good luck buddy, if you have any questions, by all means, ask away.
