spark plugs

[kingfisherman]

Hello all. I have a 1975 85 hp mercury o/b running my 1980 16 foot kingfisher boat. my question is what kind of spark plugs do i need? Also what does the gap need to be set at? I think there is some marine spark plugs would these be best or some other kind. Is there a model number i can ask for. one more thing i guess kingfisher boats arnt very popular because i never see them or hear of anyone talking about them. Thanks guys you have been so much help in the past. thanks again

Re: spark plugs

That motor was equipped with gapless spark plugs. Most plug reference charts should list the correct plug. It will be either Champion L-76V or NGK BUHW
