When I got my 1977 500 Thunderbolt 4 cylinder, the original owner said "never go out in the water without spare plugs". Having worked on 2 stroke dirtbike engines for many years, I know that when they run right, the plugs will last a while. Install the wrong plugs or mix your fuel wrong, anything is possible. He didn't have center fire plugs in it but Autolite plugs, which BTW, I had nothing but trouble with in the bikes.
On the water 3 years now with the same plugs, they are the recommended center fire plugs. I'm wondering if I shouldn't consider replacing them just for piece of mind. I pull them and fog each cylinder at the end of the season, I clean them off but they have always looked good. What do you think?
