What spark plug for my Mercury 1993 150 hp Mercury black max? The markins are not visable on the ones that are in there and all the gaps are different. Wonder what gap and which kind are the best for this motor it runs rich, I think from all the smoke when started.....<br /><br />Thank for all the help I need to buy a manual but I just bought the 1994 Robalo boat Houston TX, Man they must be proud to put that big of a sticker on the side

The NGK site calls for BU8H, which is a surface gap plug.
