My father seems to think fixing the depth finder on the Lavey is of dire importance. I'll be driving it behind a houseboat rental for a week and I'm sure we'll be using it to figure out where we beach the houseboat for the night and whatnot, aside from the usual driving it and towing a tube. I haven't been to Powell in a very long time, but I fail to see how not having a depth finder will result in us DEFINITELY destroying the prop as he seems to think. We do have a backup.
