The motor is going thru repairs, I hope it will be OK. Being that these parts (Re: Temp switch and Tag assembly) are expensive, do they need to be installed before motor is run for the first time on muffs or in a tank? Also I posted yesterday regarding motor repairs, need help please, did not receive answers yet. Title: 1987 140HP Johnson Overheat Big time. Any help would be appreciated. Thank You all in advance.
