The last couple of trips I've noticed a miss (like a fouled spark plug or something) @ around 4000 rpm's. This miss doesn't last long though. Only a second or two. It will happen at infrequint times. The last time I took it out I changed the spark plugs. It ran great for about an hour, then it happened again. A short miss at 4000 rpms. The boat starts to fall off plane then the motor picked back up and it ran fine for about 45 minutes to an hour. The fuel filter was changed in October, and I have ran Ring Free (By Yamaha) through 2 tanks of gas.
