easy out a manual release valve on trim?

[kheid]

I am going to try to grind a semi groove on the side of the screw thats all chewed up and get a bigger screwdriver on it with a hammer if that dont work im going to drill into the center with a left handed bit carefully as to not go all the way through the screw and see if that gets it out,last resort will be to hammer the screw extractor bit in the same whole and back it out and hope for the best.....talked to the marina owner and he said to just move the boat up 3 feet forward and sit a ladder across the bunks so tomorrow i will be sitting above the water on a ladder trying to get a screw out !!!!!! ha ha ha ha
