Yesterday we were heading downriver at Henderson at the Evansville/Henderson gathering and in the middle of the river the motor quit workin. We were running it wide open and it wasnt having any problems and the engine just revved up and the motor was tilting out of the water. There werent any logs when this happened and we were in the middle of the channel. The motor runs but the propeller doesnt turn. It will go in gear but just rev up and wont turn the prop. I dont think it was spinning freely in neutral and when i tried to go in reverse i couldnt shift it back. I am clueless about this stuff and I will have the other guy explain all of the details when I get him on here. Any ideas?
