So i was pulling the plugs on my boat today (85' Sunsport) and when i pulled the one for the exhaust the water was black and a bunch of sand and rocks in there, ill post a picture. This is my second winter with it and last winter i didnt pull the plugs i just brought it up to operating temp and put antifreeze in. So im just wondering if that just happened from maybe the PO beaching it or what, the boat is far from pristine so it wouldnt surprise me. Also does anyone know what tool and where to get it to get these plus out? Its a big square..boat 2.jpgboat.jpg
