I hae a '98 Honda BF90A I bought in the spring of last year. Was going to replace the spark plugs, and looking on iboats there are two plugs recommended. 1) Champion RA8HC for $3.12 ea. 2) NGK DR7EA for $32.05 ea.

What's the deal? Is the NGK plug that much better?, or is the Champion OK? Any input from anyone? Just trying to understand what I need/should do.

Also, I have replaced the lower unit oil, any other regular maintenance that I should perform? I was told the impeller was replaced shortly before I bought the motor, but cannot guarantee.

Thanks for any help.
