Hi everyone, I have a 1998 Kohler 4ESZ genset. We run it underway often but I've had one or two times that it either pulls air or for whatever reason will stop pulling cooling water. I've replaced the impeller and cleaned the HE so I think we're good but it got me thinking --

Does anyone know an easy way to tap into the temp sensor on the motor to run a remote gauge to the helm? I could also do a water pressure gauge but I'd rather stick with engine cooling temp.

If I could avoid drilling holes that would be ideal :)
