Champion QL77CC Spark Plugs

Champion QL77CC, stock number 941M. A copper core center electrode gives you accurate heat range control, which matters on an outboard that runs long stretches at load and then idles back to the dock. Corrosion resistant construction means it comes out at the next service instead of fighting you in an aluminum head.

Check the plug number against your engine manual before ordering, and change them as a set so all cylinders are working from the same baseline. Read the old plugs before you throw them out. Color and deposits on the porcelain tell you more about how that cylinder has been running than any gauge on the dash.
