Spark plugs installed on a 2005 Johnny 150hp?

[Johnny150]

Does anyone know how difficult it is to install spark plugs on a 2005 Johnson 150? I understand needing to gap the plugs, but what about indexing?

Pretty simple get a plug wrench and remove the old plugs and install the new ones, get you some champion ql78yc's (938) and gap them at .030 you will be happy. No indexing required it's a carb motor.

THANKS!

Don't overtighten them, the torque is 18-20 ft.lbs.
