Totally baffled by todays engine failure. I need help.

I was out in some rough seas today when I had a problem. I have a 2000 130hp Yamaha 2 stroke. My overheat buzzer went off and I immediatly cut the engine. I inspected the lower unit to see if I picked up a plastic bag and it was clear. Next, I checked the oil level and it was good. Just as I cut the engine, the telltale "pee" stream was present. I attempt to restart the engine and it was completely unresponsive(As if the battery had been removed, totally nothing)Is it possible for the overheat buzzer to go off for something other than overheating? It is possible I took some water into the engine, as it was very rough out there today. Could the overheat buzzer go off if there is a bad connection at the battery, or if there is a short circuit? I had to get towed back to the dock, but once there I tighened up the battery connections, and made sure the wire connections were all good and she started right up. I am truly baffled. I can see the overheat buzzer going off, but what would that have to do with the engine not restarting aferwards?

hello<br /> what visual indicators were presant on the tach at the time of the alarm? its not supposed to trigger an audible but voltage spikes due to loose battery connections and rough water can do funny things. if you must use wingnuts on the battery modify a socket by grinding slots up two sides 180* apart so you can tighten them securely.

Is it possible that water got into the enigine because of the hevay seas? If so, could water in the wrong place cause this type of problem?

Hey guys on this overheating -- <br /><br />Is there a thermostat in the engine like a car?<br /><br />Are there dual sensors - one on each head?<br /><br />If I have sucked sand into the head -- can it be back flushed?<br /><br />Dave B.

yes and yes<br /> one sensor actually a switch and one t-stat on each head, also a pressure relief<br /> post a new topic and describe your problem
