Eats plugs..

[John361v]

I have a 1989 johnson GT 150. Rebuilt in 2001. Fouls plugs every month or two,could this be from plug wires or coils breaking down?

Plug type and gap?

[John361v]

NGK BR6HS,I think the gap is .030

please read the plug chart on the top of the forums. NKG IS NOT the reccommmended plug for the motor you have Johnson and rude use Champion plugs.
recommended plug is QL77JC4 gap .030 that is for a 90degree crossflow 1988-1991

After you get the correct plugs installed, check to see that both banks are warming up to normal temps @ idle.
