2014 Mercury (Made by TOHATSU) stalls after about an hour of running. After about 1 1/2 hour it cools down and will start and run for another hour. If I take the cover off and let it idle at the dock it runs till I turn it off. The motor has 300 hours on it. The tell tale drain has good flow. The other thing if i go from forward to neutral it will sometime stall. The local dealers can' t test anything and are honest enough to say it is a matter of replacing parts.
