I went out on boat this morning around 8:30am. Water in intercostal was close to flat at start of day. Started out with only 9 hours long on engine from first to outings since Boat was delivered. I added 2.0hrs today. I had 2- engine fault shutdown warnings today. They happened about 1-hour between both events. Speed at time of both events was 28 mph, engine temp at both events was 154 degrees, rpm both times 4250. Engine shutdown default code 136. That's where I ran the engine the whole time I was out. Both times I put engine in neutral, turn ignition off for 10-15 seconds. Restarted engine. Code disappeared. Engine temp read 140degrees. Rpm at idle .500 . Both times engine operation went back to normal. After the 2 shutdown I went back to Marina and called a day.
