will this fit a mercury marine outboard engine ?

Sorry Dorman doesn't list anything for marine applications.

does this have the smooth wheel. Is this the a/c tensioner pulley. Thats the one I need

Yes it does, It,s coming with the smooth wheel, and fit a/c system.

Has anyone used this on a 4.2 V6 Chevrolet Trailblazer? This saystem says it doesnt fit but according to Oreilly Auto PArts system it does.

I always verify the part with auto zones or rock auto website just to be sure. So if the auto part distributers web site says it fine I would go with it. I have learned the hard way that amazon garage function is less than accurate.
