Plug brand/options for 35 hp Johnson Seahorse

[lakevet]

Have a 35 hp 1980 Johnson Seahorse Model J35ELCSN. What are the spark plug options for this motor? When serviced it has had NGK BZ7HS 10 plugs put in one time, next time ended up with Champion 841 (J8C). Any thoughts and any good place on line to lookup plugs?

Thanks!

I have two motors of same brand and HP. I always ran Champion spark plugs and would need to replace them 3-4 times a year. About 8 years ago I tried NGK spark plugs, I have only had to replace them once in 8 years, with the same amount of use as before!!

Thanks for the input. Anyone else? esp looking for what plug type (not just brand) and where you can look up on line. What is manufacturers recommended plug?

Thanks

Johnson recommends Champion, good mechanics use NGK. I've always run NGK's in my 2 cycle engines.

I like to put champions in the Johnson/Evinrudes. Your particular motor takes L82c

I have a very similar motor, a 1979 Johnson 35HP LS tiller (model: 35RL79A). I will look tonight and let you know what kind of plugs I am running. They were changed out last year by a shop when I was getting some work done on the motor.
