I have a 2000 25hp 3cylinder Johnson. These plugs have been in since last may. Motor gets used once a week for about 3hrs except from December to April. I think they still look good but I changed them anyway. Do you guys think they look like they should with that kind of use?
With a motor in good condition , the plugs might need to be looked at once a season.-----If you have to pull plugs 3 times a day you need to look for / repair issues with the motor !!!
No issues, I just thought I should change them and just was wondering if that is what they should look like with that kind of use. 95 percent of the time is trolling too.
