On my early spring fit-out I was perfiming the usual inspections..<br /><br />One of the new areas to look at: The through-transom screws holding the swim platform.<br /><br />I pulled the screws to inspect them and GAD! It looks like the stainless fastener actually corroded! Cheap fastener!<br /><br />There are four screws holding the platform to the transom: <br /><br />a. Three above the water line<br />b. One under the water line.<br /><br />I can see the possibility of water intrusion into the bottom fastener hole. Perhaps some wetness on the top one.<br /><br />I spun the drill in the hole--wood looked possibly damp, but not rotted.<br /><br />How do I clean this mess?<br /><br />Do I squirt acetone into the holes? What can I do to dry this mess and pot a new bolt?<br /><br />Your recommendations are GREATLY appreciated.<br /><br />Ken (Red Bank, NJ.)
