I have a boat with a 1986 Mercury Black Max 150 and I have only ever taken it in fresh water. I would like to take it out to the San Francisco bay, but I am worried about bringing it into salt water. Can any motor be used in salt water, or do they make motors specifically for salt water? Can I do any damage to it taking it into salt water? If I am able to use it in salt water, what should I do for cleaning afterwards? Just rinse everything off and run some fresh water through with some muffs? Any help is appreciated!
