    Fleetwin: Thanks for the info but this doesn’t have that hot light feature. Not in the wiring from box at stern or on the dash panel. I will be running the engine with temperature  monitoring gear on the top cylinder head and thermostat early this coming week. Trying to be ultra careful with run time, RPM and external temperatures. I wonder what else there its hiding out there to bite me in the butt!!?? Thanks  Tom Alex
