2000 200hp Saltwater series 2 stroke SX200 spark plug

[crazy charlie]

I have had this motor for 3 years.Came with brand new Champion QL78C. Runs fine but I assume time to change them. Didn't realize it came with brand new plugs so I bought NGK plugs to replace at that time.BR7HS-10 .I am assuming I purchased the correct NGK plugs at that time. Anyone know if they are correct??? or should I stick with the Champions?? Charlie

normally there is a sticker on the motor somewhere indicaing what plugs should be in it.
but a owners or service manual should give the proper information
