Suisun Bay mothball fleet, fresh to brackish water
When I was moored in Portage Bay Washington I had the the best of both worlds fresh water lake to boat in or out through the locks to salt water. I lost an exhaust elbow on my generator due to salt water. When I replaced the elbow at North Harbor Marine, they said why don't you just run the genny once your back in fresh water behind the locks, duh. So now that I'm down in the Ca Delta, The fresh water slime and algae are gone in a few hours of salt water , and I make sure to flush all of my systems using sea water including my dingy motor once back in fresh water. No divers needed except for zinks.
