Possibly taking my Champion w. 225 Evinrude down to the Choptank Bay/River, Cambridge, MD. Normally am in 100% fresh water or the top of the Chesapeake. If I put in at Cambridge, and cant get to a flush or back in fresh water for a few days, is this a problem? I wouldn't be going out into the Bay proper, but the water at the Rt.50 bridge is more salt than fresh, I believe. Thanks Larry
