Re: CHANGING SPARKPLUGS
Force comes stock with champions. Personally I would use what came in it, especially if you had good luck with the old ones. The only other option I would consider is NGK, but try to find them at an auto parts store to save some serious cash. O'Reilly's & Advance auto parts carry NGK, and AutoZone has the champions. $1.50 vs. $4 at the marine dealers
