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?
