You can do it no problem, I do it all the time. I unload and hit the deploy, then spotlock. Go park, sometimes the remote will loose the signal and say "motor not found" but the boat is still spotlocked, as soon as I get back in range it picks right back up. Most of the ramps at Tibby I doubt you would even loose signal tho.
DO NOT, REPEAT, DO NOT forget to turn the power on, she's dead as a door nail until you turn her on. I have made a habit of turning the power on and then unhooking the winch, like Rock Mike says, it sure is a bad feeling for the boat to be floating away and the motor won't deploy.
