What spark plugs do I need?

Anthony,

I have a 1985 Mercury 150 and I would like to know what the proper spark plugs are for my engine. I have looked at about three different websites and get different results. Any insight would be helpful. Thanks

I think you need NGK BU8H but I would need the engine serial# to be sure.
