[QUOTE="euroshowoff, post: 397667, member: 13100"] Few weeks ago out on the water the motor died it sounded like it wanted to start, but just couldn't turn all the way over. Fast forward to new plugs and the boat starts/idles fine. (with the exception of some cold mornings it takes a little tlc). However, once out on the water, the motor doesn't want to top out past 2800rpms, and it just falls flat...no speed or power at WOT. Motor is a 98 force 40hp 2-stroke. I pulled the plugs and tested for spark and only get spark on the bottom cylinder, i'm assuming that cylinder 2. Just looking for some troubleshooting steps to try and get some life back in the top cylinder. Compression tests all check out fine https://goo.gl/photos/Jbr6fsTJQewysndL7 https://goo.gl/photos/Y11ZYZDYnc899dak7 Video of the motor running on muffs after the spark plug install: https://goo.gl/photos/UCeV15PsQYnke441A https://goo.gl/photos/7sANsvsbEgXQdVir6 https://goo.gl/photos/QWVde2NUhKiUsbjL7 (video is under a min) [/QUOTE]
