I just rebuilt a DT2 due to extreme overheating. The entire water jacket was plugged with probably a combo of salt & aluminum compounds.
To prevent a further mishap, I want to be able to better monitor the temps. My question is what is the operating temp range for this motor and what is the best way to ensure that the motor is in this range? Also, I cannot keep my hand on the upper shaft housing where water should be circulating below the piston...too hot. Is there a "five second rule:" If you can keep your hand on the housing for more than five seconds, the motor is too cold; If you cannot keep your hand on for five seconds too hot????
I've replaced the impeller & I've got water circulation after a thorough cleaning of the water passages. I just do not know how much water is circulating. There is no tell-tale on this motor! Water is, however, spitting through the exhaust holes midway up the shaft housing.
Any help?,
