Ben, i like the idea of monitoring gearbox etc - i hadnt even thought of that.

im the same already with the Defi's, Defi water is tapped into bottom of swirl pot, where as the pectel shows whats being read at the back of the head, was going to then get the stack water on the leading side of the thermostat aswell, 3 monitored points.

oil temp defi is in the sump and with your idea the stak could cover the gearbox maybe


talking away, Ben youve helped me make up my mind on exactly what im going for, more Rainbird pestering, but atleast hes about to get paid for it
