My motor shut off while running 50 mph the other day. It didn't make any strange noises and no alarms. Voltage was good also. It wouldn't turn over. Fearing the worst I trolled back to the boat ramp and went home. Prop turned in nutrual and not in gear. Took the cover off and everything looked good. Oil was full nice color no metal shavings. Tried to start it again and no luck. It would just make a quick chunk noise as if it was going to start and that was it. Tried to turn the fly wheel several times and it wouldn't budge. Tried to start it again and it turned over and started right up. I shut it down quickly. What could be wrong? I dont think the motor is blown.
