Working on my buddy's 1995 25 Johnson and wanted to know if he bought the correct Spark plug for the application. The plugs are Autolite 4093. Are they correct?
 
The recommended spark plug is the champion QL77JC4. The autolite plug you indicated above is a comparable spark plug by a competitor. Should work OK.
