See full version: Do I Need to Fog My Boat Engine
The fuel tank must be full with an ethanol-free gas when you put the stabilizer in the fuel tank. After doing this, wait for the engine to run so that the stabilizer reaches every piston and internal part of the engine. [links]
How to do it? Yes, you guessed it right, by using the fogging technique. The process of fogging the boat engine is a preventive measure against corrosion, the development of fungus inside the engine, and the most crucial, freeze-damage.
Last on this list is freeze damage. Not only a boat’s engine but almost all the mechanical parts of a boat can go bad through freeze damage if you don’t take preventive measures. The pipes and compartments can get cracks due to the accumulation of snow. It can cause permanent damage to a boat.
You can store it only to take it out after the winter break.
Now that we have seen the problems, it’s time to see how to carry the process of fogging: more
Read the WINTERIZING post in the Eninge FAQ section and apply what sections are needed. It outlines alot about I/O drives but, basically the same applies to all engines. [links]
Fogging is accomplished by using Fogging Oil. Most hardware stores and motorcycle shops carry it.
Essentially it is spraying oil into the spark plug holes turn the engine over a few times and spray agiain and re-install plugs. It puts an oil coat on the surfaces to prevent rust, corrosion and things siezing up during storage.
Re: what does fogging motor mean
Sea Foam, in the spray can called Deep Creep, is designed specifically for that purpose. And spray some in the carb air intake also. more
It’s the process of coating the engine’s inner walls with a waxy oil so that it doesn’t rust.
Go with the remaining process of winterizing the boat’s plumbing parts and other compartments.
Remember the water hose I have listed in the products’ list? It has the purpose of cleaning the engine insides. here
more important IMO if your ski sits for long periods, more than 30 days would be my guess, but that's just a guess. more
Fogging the engine refers to spraying fogging oil directly into the cyclinders by removing the spark plugs and spraying the fogging oil through the spark plug holes. Some manuals also call for spraying the fogging oil into the engine while running by removing the airbox off the carbs and spraying the fogging oil into the carbs with the engine running. (I typically do not use the through the carb method). here
After ocean use, let the engine cool completely. Then hook up a fresh water hose to the flush port (the one at the back of the boat, next to the jet pump output works best). Start the engine, then start the water. run the engine for 3 minutes at varying low to medium RPM's. Turn off the water. Turn off the engine. Remove the sparkplugs and spray the fogging oil into each cyclinder for 5-10 seconds. [links]
AT DAYS END
1.Fogging the engine at the days end insures the circulatory water that WILL turn to steam inside the warm engine at shutdown from rusting the engines raw internal metal parts like crank journals, cylinder walls, wrist-pins, as the steam looks for a nook , cranny or spot to condensate on. Yes, after you shut off the water hose off and removed the small rubber estopper on the black air-box, You spray fogging
oil in the hole, lightly rev the motor till the oil kills the engine. The engine now is internally coated with protective oil.
2. LOOK-SMELL-TOUCH for any fuel leakage inside the engine compartment.
3. Pump a lever of grease into the PTO grease zerk fitting, this will keep out any bilge water and snug up the drive carbone.
4.Unscrew the separator filter cup and look for water or any contaminate that got in the tank and now is in the fuel circulatory route.
over time of a few trips, if it continues to appear in the cup, you may need to clean the entire fuel system.
5. GREASE is your friend. Use a brush and paint it on carbs, all cables, ect, ect. ect.
6.Vacumn out any water inside the engine compartment, place on the seat up-side down so any moisture can escape, and rinse the exterior hull. If you can get any grease up into the water tunnel, rocks and sticks may pass without damageing the impeller & wear ring.
7. lightly grease the gauges rings, front compartment seals and latches. Yes, Grease is our friend. Even the VTS boot likes it. [links]
