[QUOTE="doc1976, post: 431119, member: 13441"] okay so I got the motor running in a drum today used a 55 gal drum so it would hold plenty of water and not let the water warm up much. ran the motor for 40 minutes mostly at idle with a few revs here and there. the hottest the head got at the top was 99.5 degrees. the head by the plugs saw 104, the water cover over the t stat got to 98, and the side of the crankcase right at the seam got to 106. So i am led to believe either the thermostat is stuck in the open position or there is no thermostat at all. on a side note, the exhaust relief hole under the cowl latch was spitting out water and exhaust just like the ones in the videos so I guess the motor is pumping water fine.
