This is my first time storing the 2700, and also my first experience with an electric engine hatch. Trying to decide how to store things, and wondering what others on here do for the winter.

1). Leave the batteries in the boat or take out? I am thinking of just putting a battery tender directly on each battery (disconnected from the boat). The boat also has charging terminals beneath the battery switch. Not sure if this is just for a jump start in case of a dead battery or if they are for charging, and I have no idea how they are wired with the battery switch.
2). Leave the hatch up, down and connected to the ram, or down and disconnected. Opening the hatch while disconnected from the electric ram is a two person job (it weighs a ton and there are no handles to grab onto). I am not sure how one would open the hatch manually with the ram connected. There is a small access hatch near the ram, but not certain if it would be possible to "pull the pin" that secures the ram to the hatch.

What would you do?

I can't speak for Lake Geneva, but out here, indoor storage, I leave the battery (only 1) in the boat with the main switch off and a tender connected to the battery. This allows the guys in the warehouse to raise the out drive when they move the boat and lower it down when they are finished. Just finished the fifth season (4 winters), and the battery seems to be in excellent condition. If you do use a maintainer, be sure the electrolyte level is where it should be.

I am assuming the batteries are accessible only when the hatch is up. As far as the ram is concerned, you can experiment with the terminals that are below the main switch. Leave the ram in the up position, battery connected only to the terminals and see if the ram operates. If it does, you do not need to leave the hatch up all winter. In your de-winterization, just hook up one battery to the terminals, raise the hatch, and you are good to go. Now, if the system doesn't work this way, I can't give you any advice other than to get a helper when needed.

I noted that you would use one battery maintainer on each battery (disconnected from each other. I can't recommend using one higher current maintainer with both batteries connected in parallel. I would call and ask the maintainer manufacturer before I would assume it is OK.

Think i'd lean towards leaving them on the battery tender & connected.

How cold does it get in the garage? If it stays cold for a long time, how does that affect chargeability with a maintainer?

I've had 2 boats with an electric engine hatch . . . always left the batteries in the boat connected, etc. You could get a solar charger and plug it into the 12V outlet, making sure any switche or circuit breaker for the outlet is on.

Otherwise, you could charge up the batteries about once a month, if that is feasible. A trickle charger will also do the trick.

Also, take a look at the hatch lifting mechanism . . . sometimes there is a release pin in case the battery is dead or the lift motor fails. You could see if it is best to leave the release pin/hardware disconnected for the winter, so you can manually lift the hatch if it comes to that.

I'd buy one of the newer battery maintainer type chargers so don't have to worry about over charging.

I have always disconnected the batteries as well as the ram(s) that lifted the engine compartment. Yes it is a pain in the ash to get that engine compartment back up and at times it takes multiple people. My 320 took 3 of us. But you only have to do it once and no worries about batteries connected all winter.

Absolutely! I have several Deltran Battery Tenders - put them on anything that has a battery and is not used for extended periods of time.

The garage is not heated, so it could get -25F on a really cold winter. No idea on how the extreme cold affects the battery tender. Bringing the batteries indoors is an option (a PITA for sure, but an option).

Not sure how your ram connects to the hatch, but mine was with a 3/8" pin through a bracket on the hatch and a hole on the ram. We used to store unheated, so I took the batteries out and kept them in my garage, where it was easy to top off the charge a couple of times during the winter.

To open the hatch easily, I used a piece of 1/2" copper pipe cut to fit between the sides of the bracket on the hatch. I put a large (18") tie wrap around the pipe and then installed it on the hatch with the 3/8" pin. When I closed the hatch, I left the tie wrap hanging out, so to open the hatch, you just grabbed the tie wrap and pulled the hatch up far enough to get your fingers under the edge. Worked great and I gave it to the new owner when I sold him the boat.

I;m one of the lazy ones who leaves the batteries in, bt the A/B switch Turned off for the winter.
But, it is in the attached garage that normally stays above 50 degrees. Since the boat is so accessible I occasionally hook up the battery charger on trickle charge rather that leaving a battery tender connected.
I know when we were looking for our boat I looked at a 2000 Mastercraft with a single electric hatch that covered the whole back section. There was an access panel much like what you described that the dealer said was to be able to disconnect the ram WHEN the battery died.

I leave both batteries in the boat connected with the A/B switch off. I leave the cord for the onboard charger accessible from outside the boat for occasional charging. I guess I'm lucky as I can lift the electric engine hatch without much effort, no pins to pull. My boat does stay in a heated garage.

I don't think it's a good idea to store or charge batteries for extended periods in extreme cold. I'd be bringing them inside for the winter. If the hatch is too heavy to lift by hand, maybe a set of small temporary cable long enough to reach the floor for a battery connection when power is needed.

If a battery is fully charged it will not freeze. Have left mine in the boat for the last 4 years. I disconnect & charge then leave alone for the rest of winter. Come spring i charge again & then reconnect.

My 330 Sundancer had an electric lift on the engine hatch. When I would remove the batteries for winter months I could still raise the hatch by plugging my charger into the cigarette lighter socket.. It supplied enough juice to raise the hatch.

Another option would be to hook up a remote spot outside the engine compartment where you could attach a batter charger to the posts and use that power to raise the hatch.

Didn't think about using the 12v accessory plug to add power.

"Didn't think about using the 12v accessory plug to add power."

Just be sure the current drain is less than the rated amps for the accessory plug. Should be able to check the fuse to know for sure.

Yes, the accessory plug . . . also can be used to re-charge a dead battery enough to start the engine if need be, given enough charging time . Cars have/can do the same sort of thing.

"Cars have/can do the same sort of thing."

Except if the accessory plug is switched off when the key is "off". Which is the way our 2006 Subaru and 2012 Passat work. The Tahoe is on all the time, and it makes it convenient to charge phones, etc. even if the engine is not running.

Slightly off topic, but make sure you always close the hatch in such a way that you can pull the ram release pin. Soem day the ram may not work and if the pin is too tight to remove you will have a hassle. When I close mine, I draw it down tightly until the ram stalls, then tap the hatch button up for a moment to remove tension from the ram. If I don't do this, the pin is impossible to pull. by hand and using a tool in the access port would be challenging on my boat. You may need to experiment to find the sweet spot.

I know electric engine hatches are a luxury and many people really like them. Our boat does not have one, but it does have two pressure cylinders like we find on SUV cargo doors. In our case, they work like a charm. That may be an option for some if they don't like the electric hatch.

I have a small access hatch near the pin - but the pin needs to be installed so that the pull ring is facing the hatch. Also, not convinced that one could actually grab the pin via the hatch - might give this a try this weekend to find out. Could be one of those things you need a 5 year old with small hands and wrists to help.
