I have a Merc. 3.0L/LX I/O and with the change in the gas mix to a Alcohol blend, are the factory recommend spark plugs still ok to use? or should I switch to a cooler buring plug?.

What do you mean by alcohol? Do you mean a blend? A 10% blend would make little difference in combustion temp. Be careful with alcohol it will soften and even dissolve plastic, such as inline fuel filters and carbureator floats.
