Recently I took my boat out and ran up a river 4-5 miles. Stopped at a marina for about 10 minutes. On restarting the motor had a tremendous kick and would not crank. After several attempts it cranked and I wisely returned to my launching area; motor ran fine to that area. However, attempting once more to restart the "Kick" was very evident and motor would not start. Put it on trailer and went home. Found one sparkplug boot nicked all the way to the wire (exposed), can't see this as a kicking problem. Any ideas?
