With all of the batteries disconnected from winterization how do you get the engine hatch to lift to replace attach batteries and get ready for spring?
Thanks in advance

410 sundancer engine hatch lift

The same way you got the hatch down after disconnecting them last fall 
Can't you just apply 12v to one of the 12v sockets (for example at the helm)?
As a last resort, there is the manual way to do it, by opening the access port, pulling the pin and lifting it -- but the hatch on a 410 must be enormous

That's a beast of a hatch indeed! Manual lifting is no way to go through life.
You should be able to backfeed 12V from a cigarette lighter. I've never done it but there are many threads around here on how it can be done.

Never had this specific issues, but I did drain the batteries on the hard this winter. I tried the 12V receptacle, but couldn't get it to work. I don't think I could get enough current to flow back through.
If you pull the hatch at the helm (down low between you feet), there is a circuit breaker panel in there and the power to the hatch is on that bus. Use a good 12V battery and a set of jumper cables to power that bus. You'll need to find a good ground point though...I cant remember if there is a ground bus in that area.

I was deployed on disaster relief mission for rescue operations when my wife had the marina do this as I was not around.

bought an ac/dc adapter that plug into cig lighter from my jump pack and fed power to unit and lifted.
Thanks for the help everyone.

That's great to hear and thanks for following up!
Can you post an example of what you used? I'd like to have something on hand in case this happens. Thanks!

here is what I used, it was an electrician friend of mine that had it, but he also stated that I could remove that rocker switch for the engine hatch and run wire directly to battery jump box or even a battery if needed.

Would your hatch lift work if you turn your battery charger on? When you turn your charger on the positive leads (that used to go to your batteries) will be hot now so make sure they aren't grounded to anything. I've never tried this but it may be worth a shot. You would have to be plugged in to shore power for this to work, though.

There would be no connection to batteries so turning battery charger in wouldn’t be useful.

On a side note, does everyone disconnect their batteries when they winterize (out of the water)? I only did this once, when the marina required me to storing the boat indoors for the winter.
I leave them in the boat. There is power where I store the boat shrinkwrapped for the winter. I keep plugging in the boat, and they keep unplugging my cord a day or two later when they notice
I keep this up all winter until back in the water

This winter Mirror Image didn't disconnect the batteries but they plug the boats in every week or so. My Cobia has the batteries disconnected but left on the boat. Next year? Unknown because I don't have winter storage location determined yet.

I could not get to the boat in time to winterize one year so the marina did it for me. Spring commission I could not figure out why the engines would not turn over. I borrowed their battery jumper box, went to clip it on the batteries, which is when I noticed they had disconnected them for winterization. I reconnected them, engines fired right up.
When I asked why they disconnected them they said for safety.

I'm one of the guys that always unplugs unattended boats if I see 'em plugged in over winter. I'd prefer not have someone else's cooked batteries and/or failed charger ruin my upcoming summer...
