Customer Question

2006 25 msh yamaha. about three quarters of a mile running at half speed, once the moter warms up, the moter will start missing like its running on one cylinder. The last time it was in the water the moter started missing and we tried to get fire from both cylinders, the top was firing but the bottom was not.
