Perhaps I missed something in one of your posts…But, how is it you are determining that the powerhead is running hot? Are you judging temp based on gage readings? If so, please know that these gages or often inaccurate and are affected by high battery voltage. Did you keep the water cooled regulator/rectifier from the original turbo jet powerhead? Or, are you using the simple rectifier only system that was on the older 140 powerhead? High battery voltage drives those gage readings up giving false readings…
