    Sea-Doo 720 spark plug gap

    Like the title says I need to know the factory recommended gap for the NGK BR8ES on the 720 motor.

    Many folks set the 720 gap a little tighter because the ignition systems are weaker than the 657x or even the old yellow motors. I'm not sure what the book says on gap specs, but I would just stay on the tight side of it. So heres some jargin instead of an answer to your question but it had to be said.

    In some models there is a label on the hull where the seat hooks that tells the specs of the engine also the spark plug gap.
