I have a 250 Pro XS cowling. A friend of mine backed it into a garage when putting his boat away. Insurance replaced it. So I bought the cracked one. It would be easier to fix it if that rear cowling vent wasn't there.Short of a bomb is there anyway to get that out of there? I know that Mercury never intended it to come out because they used some serious adhesive to attach all the vents inside this cowl. Wondered if anyone had removed it and how?
