I haven't had this happen, but I would like to know because I have seen and heard it happening to people when they bring there boats out at the dock. What can you do IF you can't bring your drive back up? Can you take something off so you can manually push it up, then hold it up with straps untill you get home? My boat has an Alpha-One unit. Just curious to see the answers........JUST incase it happens, I would rather be prepared.
