Rusty, I just acquired a 2005 225 HO (non Etech) and have read and seen that they seem to be spark plug eaters. I'm used to running NGK plugs and this seems to run the Champion QC12PEP, my question is, is there a compatible plug from NGK and is it worth trying to see if they foul less and hold their gap better. This new motor makes my TR21 a whole new animal after my old 200 EFi gas guzzler and am looking to see if I can get a few more hours of smooth running out of the plugs. Appreciate any help you can give me. Thanks, Brad
