interesting idea, Terry. i have a high-water bilge alarm. i see some value in what you are describing, though. Main concern will be matching all the stuff i already have on the gauge cluster. i have an on/off/on rocker switch setup with a float switch on the units. I had plan for bilge pumps when i was doing the outboard now it's a question of the biggest (Sterndrive) going in first. I'll put this through the think-a-lator.
here's a matching light. i bought a check engine one for that center hole. now how do i modify the cluster.... Must consult the CNO. Hope she hasn't seen what I spent on UPS and Transom Assembly. Hide Me!
