Okay here is my situation. I have a 93 Chriscraft 197 Concept with a Ford 302 (5.0) with a Cobra Omc outdrive. The boat and motor and drive are in excelent condition, garage kept with cover since taken off show room floor. I am the only owner. 2 weekends ago the boat started over heating and so I pulled it off the water and replaced the water pump impellor and the "t" stat. Gaskets and seals and all that good stuff. Took it out last weekend and she ran fine for about 3 hours. Took her off the water for 5 hours or so and when we went back out, she overheated again in about 10 min of run time in the water. Now it will run fine and hold good temp, around 165 with the hose and muffs on. Checked the "t" stat housing, no leakes, checked the new impellor, looks good, everything lines up. I "think" that I have some of the old impellor lodged in the system somewhere impeading my water flow.... I plan on flushing the system this weekend. Does anyone have anyother ideas or suggestions to try? I am open to any and all advice. Thanks in advance....
