Google ( stern saver) I've used these on a couple installs. You epoxy it on so no holes drilled into your transom. I've had no feed back on how well long term it holds which means they have not come loose or I'm sure I would have heard by now. Me personally I like thru hull which picks up less turbulence at higher speeds.
