WINTERISING MERCURY EFI 100hp

[ciaranp]

Whats the best way to go about winterising my Mercury outboard.

Big bin of barrel full with water, add salt flush i got from local dealer.Flush engine at idle for 20mins, Also add a fuel conditioner while running the engine.
Spray the following http://www.3inone.com/products/silicone-spray/ on all the inside of hood? Anyone ever used this 3 in 1 spray? Can it be used to spray exterior of engine also.

When i stop flushing engine leave the Engine vertical position and should this let all the water drain off so no freezing?

I wouldn't use that stuff anywhere near a rib or anything that might ever need glueing or painting at any point in its life. Silicone sprays are the work of the devil when it comes to trying to get it off.

Use Quicksilver Corrosion Guard.

I'd still use QS Corrosion Guard-it goes on like a spray then sets so it doesn't come off.

Yes. It may attract dust and stuff on the exterior, but it comes off easily enough with a bit of soft solvent.
