Spark Plug - Is sticking with Merc plugs recommended? If going to an auto parts is ok store what brand and part number should I put in?

Impeller _ Same thought process, should I stick with Merc? If so do I need the whole kit or just the impeller. Part number would help please. If another brand is recommended which one and part number.

I always end up with the wrong part so if part numbers aren't to much to ask I would appreciate it. My first post so please bear with me. Thank you

"John, you should stick with the NGK plugs that were engineered for your motor (BUHW-2) or your result may be quite disappointing.

Merc and Yamaha ignitions throw out substantially more voltage than others, so use the correct plugs..."

Thanks Graham & Bandit for the advice on the plugs. NGK it is. How often do you recommend I change them and what gap setting? Have not changed them for a while and motor runs great.

Any advice on the impeller?
