got a 97 150 EFI , the motor is with me for just over one month so I don't really have some history of it, the guy that sold it to me said it has been sitting for 2 years, when first tried it seemed to be really overheating and there was little water coming out of the pee hole, so I changed the impeller, no big improvement, so I removed the thermostats and it got a lot better, the pee hole flow was much nicer and stronger and there was also plenty of water going out of the back exhaust hole , and since I am still waiting for the thermostats to arrive I am driving it without them till they come, but still with all that nice looking waterflow the block seems to be really hot, I dont have a thermostat on it, but I can touch it for a max of 1 second with my hand, and non of my previous motors were getting that hot, there is no alarm or issues that look like it is overheating but I am just worried, so is it normal for these v6 to get really hot ? and if not what else from the impeller and the thermostats could be wrong ?
and just to mention I almost never run it at WOT , mostly 40-60%
