Fogged Engines

I have my boat stored at Sassy Marina in heated storage. The Merc 5.7 inboards were fogged when the boat came out and wonder if there is anything special I should do besides burn off the fogging stuff when I go in April 23rd. Fuel tanks are full. This is my first boat so will appreciate any advice.

Make sure all the drain plugs in the exhaust and block have been put back in.
You shouldn't have to do anything. The fogging oil will burn off quickly. Upon the 1st startup you'll notice some white smoke for a bit.
First thing to do is stock the fridge with beer. Second would be munchies and more beer. Third would be assortment of clothes, towels, sunscreen and of course more beer.

If your in heated storage, you shouldn't have any plugs to check. Charge the batteries, and let her rip.
double check and make sure plug is in it sucks when you forget .. i know this from first hand experience.. Its good for alaugh though if your the guy on the next ramp watching..lol
. but not if its your boat..

I understand they still winterize the engines and water systems at Sassy's because if the power dies durring the winter they don't want to be liable for anybodys boat. At Schmid where I keep my boat, they recommission the boat in the spring. So when I go out it's already tied up in my well and ready to go. They may do this at Sassy's too, you'll have to ask.
Be prepared for a good amount of smoke out the exhaust pipes. This will last a good 20 - 30 minutes depending on how good of a "fog" job was done. Don't be alarmed, this is normal.
Hell, just replace the motors every year and you won't have to winterize. At least that has been my last two winters.

Hammer, I'm sure that your boat is stocked and ready to go!

I've got another question about fogging. In the past, I've always started the boat up in the spring before changing spark plugs to burn off the fogging oil. This year I have an engine out and can actually see the plugs on the one still in the boat. I'm not ready to un-winterize yet, so is there any problem changing plugs now and firing her up later? Should I be concerned with fouling the plugs?
Bill,

I do the exact same thing. Fire it up withthe old plugs, then replace them. You don't wanna sut up the new plugs.
Hey Bill,
Unfair ! No way !
You cannot put those plugs in until the other engine is installed !

Then get your double universals, special extension, modified socket, mirror, magnet and socket wrench along with the additional elbow installled between your wrist and original birth elbow, bend over feet first into that engine compartment and have at them plugs.
Afterwards replace lost skin.

Great8,

What I like to do is to crank the engine over for about five seconds with the plugs removed. This should move most of the fogging oil out either the exhaust port or out the plug hole. This seems to eliminate the heavy smoking upon start up.

Just my 2 cents worth,

Jim

I'd wait, but I've run out of donor sites for the skin replacements from changing plugs over the years.

I fog the engines in the Fall, change the plugs in the Spring while shored up, and am assured of a powerful start when she is dropped in the water. I have never had a problem doing this. The new plugs don't become fouled burning out the dried film of oil coating the cylinders (hopefully they're coated). When you fog out, the wet oil and mist fouls the plugs.

I run all Summer usually without changing plugs and she runs great (twin Chrysler 318s). I do, however, always have a spare set of plugs in case I'm off somewhere and get bad gas or the engines start running rough. This hasn't happened but I just use these spare plugs the next Spring and buy new to have as my new "spares".
Fogging is an upper cly. lube.... Won't hurt a thing....I run "marvel Mystery oil" year round ...maybe harder on plugs but easier on engine...depending on the year !!!! non leaded ot no... that way I don't need additives.....I think????????
