I have here a picture of one spark plug I pulled out. This is the worst one out of the bunch but they are all generally in the same condition. A little oily around the threads and a little carbon built up. The electrodes are still present ... Is this normal for a motor with 800hrs? Or is this indicative of a more serious issue (I:E top end needing rebuild or needing valve job)? And what spark plugs are you guys running? Boat stays between 2000 feet to 6000 feet (if it matters)https://uploads.tapatalk-cdn.com/202...1253af2086.jpghttps://uploads.tapatalk-cdn.com/202...5020e5fb23.jpg
