[QUOTE="ScottGA, post: 161218, member: 2783"] My 1983 50HP 3cy 2 stroke has that incredibly irritating alarm. From what I have been told the alarm goes off in 3 cases. 1. not enough oil. (oil system is currently bypassed and mixed manually 50:1) 2. Overheating due to no water being pumped. Brand new impeller and peeing like normal. 3. Thermostat bad. This is what I think it probably is. The motor is a little difficult to start, and the alarm doesn't start until you throttle up to about 25%. It is also a constant alarm, not a beep beep beep. I have tried to find thermostat housing with no luck. The diagrams I have seen makes it look like it is right above the 1st cylinder spark plug. Maybe I’m dumb, but just not finding it. Lastly the serial number is B13...... Thanks for any help you guys can give. [/QUOTE]
