Guys, according to the DNR here in Minnesota if you leave your boat in waters infested with zebra mussels for more than a day you should at a minimum drain all water from the boat and either pressure wash everything or let everything stand and dry out then leave it sit dry for 5 days. I don't know if their being on the safe side or not but I sure wouldn't do any less than this. If it were me I'd put some bleach in the pressure washer as well.

Gotta get back to fishin!
