SOS Mercury mark 5 boat motor

If all else fails you can do what I do when trying to clean up aluminum. Use a grinder with a cutoff and grind away until it stops sparking.

Not a good idea, what if she had magnesium and it started on fire by using the grinder. Water will not put out a magnesium fire only make it worse as soon as the water hits the fire you get an explosion of molten magnesium flying through the air igniting more flammable material nearby.

Magnesium was used in the manufacture of bombs during WWII fro this very reason, when the fore fighters tried to extinguish the flames using water they spread further.

This homemade device is from powdered magnesium which is what you would have had you used a grinder on magnesium..

Well worth the time to watch.
