Original Parts book called for (if the engine is correct)

Hurricane 350, (maker points, no electornic trigger unit) D-77V

Hurricane MK-1 (all electronic L-77V)

NGK BUH could also be used in later Hurc's

The original call by Mercury was for Surface Gap spark plugs. I don't believe that the D-6 is a surface gap plug.
