Best Spark Plugs to use?

[cigar_stub]

My Yamaha 2002 115hp 4 cylinder 2 stroke has 4 BR8SH spark plugs. I just bought the boat in the summer so I don't know how long these have been in. All is running well but I thought to replace them with new and keep the existing in the boat for emergencies.

Should I replace with the same or use something better? Any thoughts or suggestions would be appreciated.

Not sure if you have the correct plug. If you give me the exact model of your motor I can look it up. NGK plugs are very good.

Thanks for the offer Bruce. The modle number of the engine is "115XTRA".

There is no model 115XTRA for 2002. Is it possible that you have a 115TXRA? If you have that model the correct NGK spark plug is listed as BR8HS-10. The correct gap is 1.0mm.
