AS you know i got the Johnson ('62 40HP) running. Runs fine, but i'm not sure whether its cooling or not. <br /><br />I have it started up in a bucket with the water an inch or 2 below the cavitation plate.<br /><br />I did not see anything coming out the exhaust relief hole. But i'm not sure whether the motor is deep enough in water? <br /><br />Also, rite after i started it, i removed the thermostat and it was open, and then when i went to replace it it was closed again. I guess this varifies that the stat is working. <br /><br />by the way, steam came out when i removed the thermostat. i'm hoping its just not deep enough under water? <br /><br />someone please respond we are hoping to take this boat to our cottage in about 30min to and hour so i need to know! <br /><br />Thanks guys i really apprciate your help i love this website.
