Hey. Thanks. I think I first noticed the overheat sign on the engine one time after getting somewhat stuck in a sandbar. Right after this incident, after trying to get out and return to the marina that engine turned off and I arrived at the dock with its twin. I flushed them on the spot when I pulled it off the water, later dropped the leg / lower unit on its twin and saw very little sand left around the pump, cleaned it and repositioned the lower unit. Because I saw this engine on the pic with a tell tale stream, water through the propeller, and its twin had very little sand left, I assumed it was cooling fine and I decided not to check its water pump. They are due for service in October. Any advice?
