I have two gel batteries that I took out for the winter and are in my closet at home. I have never had gel batteries. I have read that they only discharge at 1% per month and they aren't harmed if you run them down.

That being said, they are nice new batteries I want to take care of. Do I need to buy an at home charger and be periodically charging them? It has been two months now since their last charge and I plan to reinstall them in may? What if anything should I be doing to keep them nice?

Second. I have an outboard that I bought with the boat. The boat was already pulled from the water when I bought it. I don't know what if any winterizing was done. The temperatures rarely get below freezing, but they do. Is my engine safe sitting on the boat out of the water or do I need to go do something to make it nice? What is the process for relaunching and getting an engine ready for use again after what will have been six months of disuse?

Thanks for all the help, as always.

For winterizing, I would fush the engine first, either by running it a few minutes at idle in a bucket of clear water or with the proprietary flush muffs. Remove the prop before running ! Afterwards disconnect the fuel line and let the engine use up the rest of the fuel inside. Once the engine has stopped, drain the carburettor (my last outboard had a little scre to allow this). Use fogging spray. Disconnect the sprak plug, slowly turn over the engine with the pull cord and spray the spark plug hole. Afterwards apply a good amount of marine grease to the prop shaft and all moving parts. I don't know if its better to change the gearbox and engine oil at the beginning or at the end of the season.

The batteries I'd probably leave on a trickle charge. If you have a solar panel on your boat connected to your battery bank then that should sort itself.

I would store the engine away from the boat if possible if not only so it doesn't get nicked at the boat yard :mad: as mine was.

No need to remove the batteries from the boat for storage. Make sure they are fully charged and disconnect the negative ..... all done. Storing them in a warm cupboard at home will not kill them but cold storage is better for them.

To winterize the outboard;
  1. connect a fresh water supply to the engine. Some engines have a hose connector, with some you use "ear muffs," and some you run in a trash barrel filled with water.
  2. start the engine, and let it warm up
  3. disconnect the fuel supply
  4. when the engine starts to sputter from lack of fuel, spray fogging oil into the carburetor and let it die.
  5. turn off the water if you used a hose to flush the engine
  6. change the engine oil (assuming that you have a 4-stroke)
  7. remove the sparkplug, and give a shot of fogging oil in each cylinder.
  8. replace the sparkplug, but do not reconnect the sparkplug wire (do that in the spring)
  9. crank the engine over 1 or 2 revolutions to spread the oil
  10. change the lower unit oil
  11. cover the engine, and put it away

The best that you can do at this point is treat it right from now on... or buy a new motor...

For a new to you engine with unknown maintenance history, change engine oil and lower unit oil (use manufacturer recommended grades), change spark plugs.

When you first use it run with fresh gasoline and bring the engine speed up slowly to check operation. Check throttle linkage and idle setting.

Test forward, neutral and reverse tied to the dock to make sure all linkages are good, then go for a short run to check operation under load.

If you don't know the history on filter or fuel, flush/clean/replace filter cartridge and drain fuel from tank, then use new fuel. Check for sediment/debris in the tank and tank fuel pick-up.
