let me just say the NGK is one plug i hate and see more problems with than any other to me they are the junk plugs of the market.

Unless it's a rice burner. I've tried CHAMPIONS in YAMAHA's before and they ran like crap, swapped in NGK's and ran like a champ again. MERCRY's have been hit or miss for me with which ones run best. But OMC's HAT NGK's with a PASSION! Larger WAL-MARTS also carry marine plugs for even cheaper than the auto parts stores.
