Location: Wausau | Is it necessary to Fog a 2 stroke before it goes to sleep for the winter? If so what is the best way to do this yourself, I am getting tired of paying the local marina for doing this. Also do you guys leave your batteries in the boat on the charger for the winter or do you pull them for warm storage? |

Location: Mt. Zion, IL | I drilled a hole in the airbox just big enough for the straw to fit in. Spray the engine fog in the hole. The whole process takes about 15 minutes the first time and 5 minutes each year after that. Also be sure to use StaBil in the gas. I always run my 2 stroke out of gas completely to prevent any damage to the carbs. As far as batteries, I fill them up, charge them on a trickle charger, and store them in the garage (heated). In the spring hit the batteries with the trickle charger before the first use and you are good to use normally the rest of the season. My last TM battery lasted 9 full seasons doing this. |

Location: Iowa Great Lakes | I never fog mine, run a can of sea foam through it late in the season add a bottle of sty bil in the last tank and make sure its topped off after the last trip out. Mine hates to start in the spring after being fogged. I also pull the batteries and have my 3 bank set up to be easily removed and hooked up indoors in the winter.

Location: north central wisconsin | Jeremy, fogging is pretty simple, as stated. Just take the air filter off the carbs and spray(while running) into each cylindar evenly for 3 or 4 seconds after it kills the motor. Take each spark plug out and spray for a couple seconds there as well, replace plugs and store.
Your batteries are truly best off right in your boat, in cold storage. the batteries will discharge less in the cold than they do in your basement or garage, and require less maintenance over winter. Make sure they are full, and charge them up before storage, and be sure they are completey disconnected from anything that could 'draw' (all accessories/ outboard/trolling motor etc.) Maybe a one time charge at mid winter and good till spring(they'll take hardly any time at all to charge mid winter if in good cond.). If brought indoors, you'll need to check fluid levels and charge a bit more often as the batteries will discharge/remain active in the heat a bit more than they will, being dormant, in cold storage. |

Location: Elk River, Minnesota | The old OMC motors from the 90's had a really slick system for fogging. They had an actual inlet on the side behind the carbs that you hooked up to like a tire inlet. Then, as motor was running, fogg it until it dies. Then add some to each cylinder and turn the motor over to coat the interior of the cylinder bore.
Since I no longer have that type of motor, I just run stabil for the last tank of gas, then when done for the season, pull the plugs and put fogging oil in each cylinder, and turn the engine over a couple of times, then spray again. Plugs back in and engine is done. So far (knock on wood) I have not had any issues in 4 years with the motor...starts up and purrs like a kitten in the spring.

| What I have been taught about snowmobile engines I would imagine applies to all 2-strokes. If you don't provide some lubrication for the cylinder walls and crank case over and above the oil in the gas you can get rust on the walls or worse in the bearings when those items go dry from long storage. The reason for fogging, and not just spraying down the plug holes, is that it is probably more important to protect the bearings. If you get a touch of rust on the cylinders walls and run the engine it might only loose you some compression. If you get a little rust on the bearings you are likely looking at tearing the motor down after the rust scores the bearing. |

bchunter - as pretty much everybody has said, the answer is YES. IMO if you can leave your charger plugged in...if it's a 2/3 bank type charger.
I also live in Wausau and can help you with the winterization if you'd like. Just pM me. |
