For all of you optimax users, what plugs do you guys run? Do you all run the plugs that mercury recommends which are about $15 a piece or do you use cheaper alternatives. I have a 2005 opti 150 and plan to replace the plugs this spring. I also here that you need a special wrench to get at plugs 5 and 6 so you have to have a dealer do it. Any truth to that?
